Asymmetric zinc-catalyzed hydrosilylation of ketones and the effect of carboxylate on the enantioselectivity

Chirality. 2013 May;25(5):275-80. doi: 10.1002/chir.22137.

Abstract

Several chiral ligands containing (R,R)-diaminocyclohexane moieties and pyrrole, furan, or benzene have been synthesized. These ligands were tested in enantioselective zinc-catalyzed hydrosilylation reactions; excellent enantioselectivities were obtained when the ligands containing (R,R)-diaminocyclohexane moieties and furan rings were used. For comparison, zinc chloride combined with different potassium carboxylate salts and ligands were also tested for catalytic hydrosilylation reactions.
