  • Title: New P,N-ferrocenyl ligands for the asymmetric Ir-catalyzed hydrogenation of imines.
    Author: Cheemala MN, Knochel P.
    Journal: Org Lett; 2007 Aug 02; 9(16):3089-92. PubMed ID: 17616202.
    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.
