CHEMISTRY BY MARYE ANNE FOX Department of Chemistry University of Texas, Austin Austin, Tex. " Alkoxide ligands, acting as pi donors to stabilize early transition metals in high oxidation states, and carbonyls, acting as pi acceptors to stabilize late transition elements in low oxidation states, provide complementary ligand effects to inorganic clusters. A recent article summarizes the effect of such ligands in controlling substrate binding; electronic saturation, and stenc control in organo

In the last several years, theory has moved beyond gas-phase quantum mechanics to provide a quantitatively meaningful picture of structure and reactions in solution. The methodology has been applied to a number of important liquid phase problems: thermodynamics, conformational equilibration, binding and recognition, and prediction of reactivity.
