Chiral counteranion-aided asymmetric hydrogenation of acyclic imines.
When combined with a chiral phosphate counteranion, a chiral diamine-ligated Ir(III) catalyst displayed excellent enantioselectivities in the asymmetric hydrogenation of a wide range of acyclic imines, affording chiral amines in up to 99% ee.
