Israel Chemical Society awards prizes




The israel chemical society (ics) prizes will be awarded this week at the opening ceremony of the annual meeting of the society on Feb. 5. The winners are Moshe Shapiro from the Weizmann Institute of Science and Sason Shaik from Hebrew University.

Shaik will receive the ICS Prize for 2000 for his seminal work in the area of chemical reactivity and bonding. Shaik is a professor in the department of organic chemistry at Hebrew University. He was a student of Nicolaos D. Epiotis at the University of Washington and a postdoctoral fellow under Nobel Laureate Roald Hoffmann at Cornell University.

Shaik has been a leading proponent of valence-bond theory and of curve-crossing models to explain chemical bonding and reactivity. This approach is quite different from the conventional Woodward-Hoffmann approach, which is based on molecular orbital theory. Valence-bond theory permits insights into bonding and reactivity that maybe obscured by the molecular orbital model.

According to colleagues, he has shaken the world of organic chemistry with his valence-bond view of electron delocalization in aromatic compounds and made chemists think about aromatic delocalization in a completely new light. Recently, Shaik has made innovative contributions to the bonding description of metal oxo species and on the biological oxidation of hydrocarbons by cytochrome P450.
