摘要：
Disclosed are novel ruthenium compounds of formula (Ia) and (Ib): wherein R1 and the moiety are defined herein. Also disclosed is a process for using these novel ruthenium compounds as catalysts for asymmetric hydrogenation and transfer hydrogenation of ketones with high reactivities and excellent selectivities.
