13. SUMMARY OF RESEARCH ACHIEVEMENTS 1981-on

Here are the major works:

(a) Valence Bond (VB) Model of Chemical Reactions: What is the origin of the barrier in chemical reactions? Why some reactions are stepwise while others are concerted single-step reactions? Is it possible to estimate barriers, solvent effects, and predict stereoselectivity, regioselectivity, and transition state (TS) structures, for a broad range of reactions in some simple and yet predictive manners? Is microscopic reversibility always obeyed? How do photochemical reactions proceed? We have created such a predictive system of thought using VB theory, which provides more accessible insight into reactivity than other theories (e.g., molecular orbital theory, or DFT). While doing so, I also revived VB theory and projected its beauty and utility to the community. The chemical-reactivity work started in 1981 and has ever since been published well over 100 papers, reviews and two books, in which I demonstrated the wide-ranging and unified applicability of the model, from simple reactions like H + H2, through organic reactions and reaction mechanisms, and all the way to reactivity and mechanisms of metallo-enzymes. All this insight is gained using just two types of VB diagrams. The spine of the diagram is the avoided crossing of the principal VB-state curves, which describe the interchange of the bonds in reactants and products during the transformation. The avoided crossing creates a barrier, with a height that is proportional to the promotion energy gap between the state curves at the reactants and products geometries. The avoided crossing energy term (coupling betweenthe state-curves) determines the stereochemistry and structure of the TS. There are other excited states, which can either mix into the TS of the concerted reaction, or fall below the crossing point of the principal curves and thereby generate reaction intermediates. These VB diagrams provide additionally a link between thermal and photochemical reactions, and enable one to derive the chemical structures of conical intersections as a general mechanism for photochemistry. Despite the theoretical rigor of the model, it achieves all this insight in a pictorial and an easy-to-use manner. The recent VB treatments of the reactions catalyzed by Cytochrome P450, and of hydrogen-atom transfer (HAT) reactivity across the board including a derivation of a predictive expression for identity H-abstraction barriers, and the unification of HAT and proton-coupled electron transfer (PCET), demonstrate the versatility and unifying power of this model.

 

(b) A New Outlook of the Chemical Icon Benzene and Electronic Delocalization: Benzene is a chemical icon, and most chemists believe that it has a uniform D6h symmetry and special stability because the electrons prefer to be delocalize and hence driving the molecule to adopt a D6h symmetric structure. In 1984 I questioned this dogma and showed that for any number of electrons that can undergo delocalization in a uniform symmetric structure, one could find a series of isoelectronic species in which the delocalized species are either unstable TSs or stable-delocalized clusters. The nature of these species can be predicted from the promotion energy gap in the corresponding VB diagram traced along the localizing distortion. When this promotion-energy quantity is large, as in H2, all the uniform Hn species (e.g., D6h H6) will be TSs of the respective bond exchange reactions, while when this quantity is small as e.g., in Li2 (and other metallic dimers), the Lin species will be a stable cluster with delocalized electrons. I showed that this promotion-energy quantity is large for π-bonds, and therefore all the delocalized π- electronic systems like the one in benzene must behave like TSs, trapped by their frames of sigma-bonds in uniform-symmetric structures (e.g., D6h benzene). My co-workers [primarily Hiberty from Orsay] and I have changed the view on these chemical icons and showed that these π-species possess a duality; on the one hand the π-delocalization stabilizes the molecule, and on the other, they behave as distortive π-TSs trapped and blocked by their sigma frames. I then went a step further, and showed that the distortivity of these π-TSs causes their twin-excited states (which arise due to avoided crossing along the localizing coordinate) to possess an exalted frequency of the localized mode. Thus, if you disrupt the delocalized π-electrons of benzene by exciting it to the 1B2u excited state you will find that the b2u mode is selectively exalted from 1309 to 1570 cm-1. You weaken π-bonding and the frequency increase, quite surprising! This new outlook completely changed the understanding of these molecules and opened new vistas to their unique twin-excited states, and provided a link between Kekulé structures and experimental observables

.

 

(c) Entangled Reactivity and Breakdown of Microscopic Reversibility: My coworkers and I questioned the outer-sphere electron transfer mechanism in molecular chemistry and developed the alternative bonded electron-transfer model. We demonstrated that this model brings about entangledreactivity, which leads to the breakdown of microscopic reversibility. Electron transfer (ET) reactions have a common set of VB states as the respective ‘polar reactions’ in which bonds are broken and made. Starting 1995, we have shown that the VB mixing and avoided crossing of these states for reactions of donors (nucleophiles) and acceptors (electrophiles) are completely entangled. Consequently, a series of reaction will exhibit mechanistic crossover from ‘polar’ to ET reactions, and in the intermediate region of this crossover, the TSs will be common for both mechanisms, such that a single TS will serve two mechanism and will lead to two different products, in violation of microscopic reversibility. In fact, entangled reactivity and breakdown of microscopic reversibility should be common, and are expected whenever two mechanisms share a common set of VB-states (e.g., SN1-SN2, E1-E2-E1CB, etc.)

 

(d) Two-State Reactivity (TSR) and Multi-State Reactivity (MSR) in Bioinorganic and Enzymatic Chemistry: In 1994 I shifted my interest to reactions of transition metal complexes, which are important in oxidative chemistry of metallo-enzymes, like Cytochrome P450. These complexes have a variety of different spin- and electromeric states, which are either degenerate or condensed into a small energy span. There were puzzles but no answers or models to comprehend these puzzles and predict their patterns. For example, why was FeO+ a very poor oxidant for H2 despite the fact that the reaction was spin conserving, highly exothermic, and had no symmetry or other restriction on the reaction? What was the reason that the oxidation of alkane by P450 proceeded in a stepwise reaction via radical intermediates, despite the available very exothermic concerted pathway? And why these intermediates had lifetimes shorter than those of transition states? We have shown that the reactions proceeded on different spin-state surfaces, and this two-states reactivity (TSR) leads to immediate solutions of these puzzles. Thus, for example, the two states in P450 are parallel roots, one of which leads to normally lived radicals and the other to effectively concerted reactions (with zero radical lifetime). Consideration of TSR and MSR scenarios enriches the scope of chemical reactivity patterns and opens up a new mechanistic territory on the role of spins in chemical reactivity. Furthermore, spin-state crossing results in internal catalysis of many bioinorganic reactions. These ideas and many others were published in several reviews and reoriented the field and defined its cutting edge.

 

(e) New Reactivity paradigms: Exchange-Enhanced Reactivity (EER): Why does nature use nonheme iron enzymes with active species in a high-spin (S = 2) electronic configuration? This puzzle has been posed by the alpha-ketoglutarate mediated nonheme enzymes, which can bring about the activation of the strongest of C-H bonds (e.g. in methane and taurine). Addressing this puzzle by my coworkers and I resulted in the formulation of the EER principle of reactivity. Thus, we showed that when the enzyme activates the C-H bond, this enriches the metal‘s d-block orbitals by a single electron. In the high-spin state, e.g. S=2 of FeIVO complexes, with four identical-spin electrons, this added electron goes into a vacant d-orbital and causes a dramatic increase the exchange-interaction. This results in lowering of electron-electron repulsion (by ca. 50 kcal/mol) and a drastic lowering of the reaction barrier. By contrast, on lower spin-states, the exchange is depleted and the barriers are high. The derivation of the EER principle was shown to be attended orbital selection rules, which control the structure of the TS. The EER concept emerges as a key principle for understanding the origins of spin-state selectivity, and the reason why nature has selected nonheme enzymes with an S = 2 state, which proceeds via the EER pathway. EER is a chemical law of nature!

 

(f) New Bonding paradigms: Charge-Shift Bonding (CSB): The conceptual element from which an entire chemical universe can be constructed is the chemical bond. As such, the bond is the “quantum building block” of the grand scheme of “LEGO” by which practicing chemists devise and control the formation of new molecules of ever increasing complexity and beauty. My collaborators (foremost, Hiberty) and I have pointed out that in addition to the classical covalent and ionic bonds, there exist a family of bonds that have never before been recognized. These are the charge-shift bonds (CSB) in which the binding does not arise from either the covalent- or the ionic-VB states, but from their resonance interaction (i.e. the coupling between the two VB states). Thus, whenever the atoms which engage in bonding suffer a steep rise in the kinetic energy during the process (e.g., dues to atomic shrinkage in bonding, and to Pauli repulsions of the bond with lone pairs or other bond pairs), the bonding will be brought about by charge-shift resonance, since this coupling term contributes “negative kinetic energy” that enables to restore the virial ratio and establish a bond in equilibrium. CSBs occur, inter alia, for electronegative and lone-pair rich atoms (e.g., in F2), and for bonds the inverted bond in [1.1.1] propellane that are subject to large Pauli repulsion. We have shown that CSBs have experimental manifestations and the charge-shift resonance energy can even be quantified from experiments. The work will change the mental map of the chemical bond.

 

(g) The Triplet Bond - Bonding of Parallel Spins: Ever since 1999, I began to describe no-pair ferromagnetic (NPFM) bonds that hold together monovalent metallic atoms using exclusively parallel spins. Thus, without any traditional electron-pair-bonds, the bonding energy per two atoms in these clusters can nevertheless reach 40 kcal mol-1! The VB modeling shows that this bonding motif arises from bound triplet electron pairs (hence may be called, the Triplet Bond) that are delocalized over all the close neighbors of a given atom in the cluster. The VB model shows the origins of the tendency of NPFM clusters to assume polyhedral shapes with rather high symmetry, and for the very steep rise of the bonding energy with cluster size. The advent of NPFM clusters offers new horizons in chemical bonding, and in chemistry of highly magnetic species, sensitive to magnetic and electric fields.

 

(h) Quadruple Bonds in Carbon and Other 1st Row Main Elements: Recently, we showed that C2 and other isoelectronic species break the glass ceiling of multiple bonding and have quadruple bonds. This changes a fundamental dogma in chemistry, which is rooted in the early 20th century.

 

(i) Weak Intermolecular Interactions: § My coworkers and I have developed VB-based models which lead to a lucid understanding of weak interactions, which glue mesoscopic and macroscopic materials, such as dihydrogen interactions and halogen-bonds”.

 

Among the many other achievements, our group made fundamental contributions to understanding of catalytic cycles, usage of KIEs and tunneling to probe the identity of the reactive spin state in enzymatic and bioinorganic H-abstractions, the usage of oriented external electric field as catalysts and means of control in chemical and enzymatic reactivity, and finding a new mechanism of DNA repair, which was spotlighted by the journal.

 

Major research achievements are listed below. Publication numbers referring to the list of publication are indicated in parentheses:

(a) 1981-2011: A valence bond approach to reactivity.

• The work started with a theoretical paper, published in 1981 (#23) and has evolved throughout the years into a unified system of thought about chemical reactivity, summarized in reviews, chapters and books (#150, 304). The works has been incorporated into textbooks and have led to revival of VB theory in chemistry.

• The work was characterized by R. Hoffmann as a main contribution to the renaissance in valence bond theory (R. Hoffmann, Chemistry in Britain, March 1991, Letters section).

• The VB model has been incorporated into a leading text book, T.H. Lowry, S. Richardson, "Mechanism and Theory in Organic Chemistry", 3rd Ed 1987 (introductory page ix, and pp 218-223, 229, 354-360, 371, 381-382, 412, 604-608, 659, 685, 769).

• The VB model has been incorporated into a leading monograph, L. Eberson, "Electron Transfer Reactions in Organic Chemistry", 1987 (pp 8 ( the model is introduced as "An alternative to the Marcus model...") pp, 23-25, 95, 141-142, 193).

• The work has been incorporated into an advanced organic chemistry text, F. A. Carroll, "Perspectives on Structure and Mechanism in Organic Chemistry", Brooks/Cole Publ Co 1998 ( pp 213, 227, 265, 301, 497, 506-511, 740, 879).

---------------------------------------------------------------------------------------------------------

(b) Bonded Electron Transfer Transition States and Selection Rules.

• The work started with a derivation of orbital selection rules for transition states of electron transfer reactions vis-•-vis their bond making analogs. Its application in the reactivity of radical anions has resulted in exciting results (#124,130,133,141) that are entirely different than those predicted by the outer•sphere theory of Marcus. These results involve entangled reactivity and breakdown of microscopic reversibility (#314).

• The work has been reviewed recently in the highlight section of Angewandte Chemie:H. Zipse, Angew. Chem. Int. Edit. Engl. 1997, 36, 1697.

-----------------------------------------------------------------------------------------------------------

(c) Is electronic delocalization a driving force of bonding and structure?

• The work has started in a 1984 paper (#41), which tried to provide a unified model for assessing the stability of delocalized clusters and species. It turns out that one can (41,63,139,191) conceptualize all these species, stale clusters all the way to transition states of chemical reaction using a single organizing quantity, the promotion energy gap in the VB diagram. Based on this it was possible to predict that the π-electronic components of molecules like benzene, allyl and so on are transition states that are trapped by their σ-frames in structures with uniform C-C bond lengths, and are delocalized only because of this constraint (# 139,191). The model was extended to the twin-excited states and led to the development of structural and spectroscopic probes f the distortivity (#191). To cite Schleyer: The once controversial idea that the geometry of benzene and other molecular icons is determined by the σ−frame, while the π- electronic system in fact prefers a distorted geometry has become widely accepted (P.v.R Schleyer, Chem. Rev. 2001, 101, 1117).

• The work has been reviewed as a highlight in CHEMTRACTS: J. K. Burdett, CHEMTRACTS- INORGANIC CHEMISTRY, 1991, 3, 57-61.

• The work has been chosen as one chapter of a total of 17 written as a dialogue between a young and an old scientist on the status of the theory of chemical bonding ("perhaps we should take some aspects of chemical bonding, each of importance to chemists and study them the same way Hume-Ruther•s characters did [in their dialogue]"). J.K. Burdett, "Chemical Bonding A Dialog", 1997 (Chapter 12: "Is Delocalization of Electrons Always Stabilizing? Or, Why is Benzene a Regular Hexagon?").

• The work has been mentioned in the letters section of C&E News, April 4, 1996 (p 4, "Proper Benzene Citation" by, R. Hoffmann and J. P. Dinnocenzo).

-------------------------------------------------------------------------------------------------------

(d) The Twin-States Concept

1981 (# 23): Development of a general reactivity model that highlighted the importance and generality of the excited state that is the twin of the transition state.

• 1996-1998: Development of ideas associated with transition state spectroscopy (publications # 128, 131, 139, 150).

• 1996: The twin-states are made from the same electronic constituents and likely to possess coincident geometries. For a given transition state there should exist a twin-excited state that is bound along the reaction coordinate (of the ground state reaction). This twin-excited state, which possesses a coincident geometry with the transition sate, provides the entry and means to obtain spectral information on the transition state.

• 1998: Demonstration (# 153; with S. Zilberg, Y. Haas) that the transition state for the semibullvalene rearrangement possesses a twin-state at a coincident geometry and the reaction coordinate mode is positive and of an exalted frequency.

--------------------------------------------------------------------------------------------------------------

(e) Development of new bonding paradigms and prediction of their chemical

manifestations:

• 1992-1999 (with P.C. Hiberty): Charge-shift is a bonding form (#92,212,215,282), which was discovered by computational means, and is neither covalent nor ionic. The bonding is sustained totally by the resonance between the two forms. This bonding flavor characterizes both homo-nuclear bonds (F-F, O-O, N-N etc) and heteronuclear bonds (Si-Cl, etc), and appears to be the most ubiquitous bonding mechanism in chemistry. It is manifested in the behavior in condensed phase (e.g., the ever elusive silicenium ion), and is responsible for the aggregation of higher-row elements in hypercoordinated species, and for the observation of bonds with "no density".

• 1999: Ferromagnetic bonding is a bonding form, which is responsible for the stability of high-spin clusters of alkali metals, which possess no electron pairs. It is also called "No Pair Bonding". The bonding energy increases with cluster size and can sustain large magnetic clusters (#157, 212, 282).

• 2006: Showing (with Hiberty and Wu) that the covalent-ionic resonance energy of bonds is a measurable quantity.

• 2010-2011: (with Hiberty and Wu): Showing that the inverted C-C bond in [1.1,1] propellane is a charge shift bond. Showing that 16 C-C bonds fall into two groups, one classically covalent, the other charge-shifted.

(g) Development of valence bond methods.

• 1998-present (with W. Wu): Two methods were developed in which the valence bond (VB) energy is scaled to that of density functional theory. In this manner, one obtains methods which, on the one hand, include dynamic electron correlation (absent from most VB methods), and on the other hand, are economical in terms of computing time and enabling thereby application to large molecules (e.g., C30H32) and to excited states.

• Development (with W. Wu) of advanced but economical VB methods; VBCI, VBPTn, and VBPCM, capable of treating reactions in solution.

------------------------------------------------------------------------------------------------------

(f) Developing the concept of the TSR (two-state reactivity concept) in catalytic CH/

C-C bond activation by metal Oxo reagents (with H. Schwarz and D. Schroeder).

• The TSR concept was developed as an answer to a set of puzzling reactivity patterns in the activation of H-H and C-H bonds by FeO+ and other metal-oxo cations (#114,126, 176). The initial ideas developed into a wide-ranging paradigm in bond activation (#176).

• The TSR concept was reviewed in the highlight section of Angewandte Chemie, D.A. Plattner, Angew. Chem. Int. Edit. Engl., 1999, 38, 82.

• The concept paper (# 142), which introduced two-state reactivity into the enzyme field, was chosen as among the 20 most highly cited concept papers since the establishment of the journal.

------------------------------------------------------------------------------------------------------

(g) A Theory of Reactivity of Cytochrome P450 and Heme Enzymes:

• Since 1998, I introduced two new paradigms into the field: (i) two-state reactivity (TSR), whereby the different spin states of the active species produce different products in predictable proportion (#183,284). This paradigm has already resolved a major controversy in the area of hydroxylation by P450, and is applicable to other oxidative processes, (ii) the chameleon oxidant concept: that describes the behavior of the active species of the enzyme, so-called Compound I that adopts its geometry and electronic structure to the specific protein environment (#187,196,219). We postulated and demonstrated that the interaction of the protein environment with the chameleonic nature of Compound I serves as means by which the enzyme modulates its selectivity. The chameleon oxidant concept shows a potential to reorient this field of enzymatic catalysis.

• The work of the group on the mechanism of P450 hydroxylation and the structure of Compound I was highlighted in Chemistry and Chemical Industry, 2001, 54-6, 680 (the Japanese equivalent of Chem. Eng. News).

• A recent review by one of the P450 field•s leaders (P.R. Ortiz de Montellano, J.J. de Vos, Nat. Prod. 2002, 19, 471-499) write about the two-state reactivity work: "This mechanism is at once as complex, intriguing and satisfying as the chemistry of the P450 enzymes themselves", and ends his review article in the following statement: "Perhaps one of the most useful advances in the recent past has come from computational chemistry, which has provided a two-state reactivity model that readiliy rationalizes the experimental data.".

• The recent reviews of the group were selected; one ( # 267) as one of the 6 yearly papers defined as Editor•s Choice, the other (#284) as "A Hot Paper Selection for the Month of November" (See: Citing URL http://www.esitopics.com/nhp/2006/november-06-Shaik-Kumar-deVisser-Altun-Thiel.html ).
During 2005-2007, paper #289 has been featured thrice in the ACS publication list of "Hot papers":

---------------------------------------------------------------------------------------------------------------------

(h) The derivation of "spin inversion" mechanisms in triplet organic reactions.

1978-1981: This work (publications # 12, 15-17) was the first attempt to handle the stereochemistry of triplet photoreactions in a uniform manner, and followed the pioneering study of Salem and Rowland on spin-orbit coupling (SOC) in organic diradicals. The SOC interaction that causes the singlet to triplet (or vice versa) transitions has been converted into molecular distortions typified by type and symmetry, and which are encoded into the stereochemistry of the products. Many unusual features (such as formation of highly strained molecules and the heightened sensitivity to steric effects [more so than in equilibrium conditions] of triplet photochemistry were shown to result from a blend of these mechanisms in a predictable manner.

• The theory was mentioned on p 1024 in T.H. Lowry, S. Richardson, "Mechanism andTheory in Organic Chemistry", 3rd Ed 1987. ). The full potential of the work remains however unexplored.

----------------------------------------------------------------------------------------------------------

(i) Conceptualization and design of "Organic Metals"

• 1982: The electronic structure of organic metals made from donor acceptor pairs was analyzed, and the localization mechanisms in them were elucidated. The relation between an organic metal and an isomeric charge transfer complex was outlined. It was concluded that an organic metal is the thermodynamically less stable form and should be preferred under nonequilibrium conditions (publication # 30, 51).

• 1982-1992: The ideas of this work have formed a basis for the experimental research of the "Organic Metals Group" at Ben-Gurion University. The organization of the group was initiated by S. Shaik in 1982 when the field of materials and molecular devices in Israel was more or less embryonic. The key ideas of the group were outlined in a seminal 1983 paper in JACS (publication # 36) and are still of relevance to the field of molecular electronics.

The seminal study (#30) that that preceded the strategic idea of preparing "molecular metals" (#36) was formulated some 15 years before the current surge of nanochemistry.

14. SUMMARY OF CURRENT RESEARCH ACTIVITY

• Progress in chemistry relies on new paradigms and concepts. My goal is to use quantum chemistry in order to develop new paradigms, which can create order in existing data, and make predictions, which guide experiment in new directions.

• Simultaneously with this interest in novel concepts we are also engaged in the examination and shake-up of established concepts, which dictate our current chemical thinking.

• My research problems range from bonding in small molecules to materials and enzymes.

The current research in our group involves a few topics:

(a) New aspects of two-state reactivity (TSR) and multi-state reactivity (MSR). The idea is to devise criteria whereby experimentalists can probe TSR/MSR situations. To this end, we have formulated a blended-TSR theory, which interacts with experimental data and enables to probe TSR/MSR. A recent application to the L. Que catalysts shows that this approach has a potential of making sense of experimental data and spotting TSR situations. Another is a kinetic isotope effect (KIE) probe; here too we have formulated a blended KIE for TSR/MSR situations, and we are trying now to use it for making predictions and testing unusual KIE results obtained in the Que group. In addition, we are exploring new probes on TSR/MSR scenarios • magnetic and electric field dependent stereoselectivity and regioselectivity. Some of our results show spectacular effects.

(b) The group is involved in collaborative research (with R. Neumann) on catalysts made from the poloxometalate cages, which are large systems that are challenging to compute and to understand. We are trying to design new catalysts by computations. Here too there are TSR situations, unusual solvent effects, and a potential for use of electric fields to orient reactivity. Very exciting field!

(c) A major effort of the group goes to the investigation of heme enzymes, human P450s, where we try to understand the essence of cooperative binding in drug metabolism and to design de novo new isozymes, horseradish peroxidase and itspotential conversion to a monooxygentaing enzyme, chloroperoxidase, myoglobin, nitric oxide synathase (where we try to understand the odd electron problem in the second half reaction. In addition we are investigating natural systems like bleomycins, which use iron complexes and exhibit anti carcinogenic activity. All these system have catalytic cycles with many species that are interesting, and all function by means of TSR/MSR.

(d) Part of the group is involved in chemical catalysis by transition metal complexes (e.g., cross coupling, Heck reactions, Rhodium catalysts, etc). A major effort goes to the derivation of a mathematical model for catalytic cycles.

(e) Research on VB ideas continues in the lab, especially on the new bonding ideas (charge-shift bonding, no-pair bonding) and bonding periodicity in metallic clusters.

(f) The group collaborates with W. Wu (Xiamen group) on development of VB methods and their application to chemical reactions.
