Abstract
A new chiral tridentate ligand containing two phosphines and one pyrid ine is effective for Ru-catalyzed asymmetric hydrosilylation of simple ketones (47-66% ee). Ruthenium complexes with either chiral tridentat e nitrogen ligands or chiral bidentate phosphorus ligands are either i nactive or non-selective for asymmetric hydrosilylation. This work has set a foundation for the asymmetric catalytic reactions based on chir al mixed P-N tridentate ligands. (C) 1997 Elsevier Science S.A.
