Asymmetrische Katalysen, 39. Mitt.: Monohydrosilane in der enantioselektiven katalytischen Hydrosilylierung prochiraler Ketone

摘要

The reactivity of several monohydrosilane/complex systems in the hydrosilylation of acetophenone and benzylmethylketone was investigated. The active systems were modified by addition of optically active ligands and used as enantioselectivein-situcatalysts for the hydrosilylation of the above prochiral ketones which on hydrolysis gave α-phenylethanol and α-benzylethanol in up to 18 e
