title: New P,N-ferrocenyl ligands for the asymmetric Ir-catalyzed hydrogenation of imines.
abstract: The Ir-catalyzed enantioselective hydrogenation of various N-(3,5-dimethyl-4-methoxy)phenylimines was performed under mild conditions in the presence of new P,N-ferrocenyl iridium complexes leading to (R)-N-(3,5-dimethyl-4-methoxy)phenylamines in high yields and enantioselectivities (up to 99%). These chiral aryl amines can be readily deprotected using Ce(NH4)2(NO3)6.
