title: Enantioselective zinc-catalyzed hydrosilylation of ketones using pybox or pybim ligands.
abstract: The combination of ZnEt(2) and chiral pyridinebisoxazoline (pybox) or pyridinebisimidazoline (pybim) ligands catalyzed the asymmetric hydrosilylation of aryl, alkyl, cyclic, heterocyclic, and aliphatic ketones. Under mild conditions, high yields and good enantioselectivities were achieved. ESI measurements allowed for the characterization of the active catalyst.
