Findings
Ru(L)(X)2 complexes were successfully synthesized and characterized.
Ru(BINAP)(OMs)2 outperformed Ru(BINAP)(OAc)2 in catalytic asymmetric hydrogenation.
Anion variation significantly impacts catalytic performance in these reactions.
Abstract
A series of Ru(L)(X)2 complexes (L = bidentate ligand; X = OMs, OTs, OTf) was synthesized and characterized. Ru(BINAP)(OMs)2 showed improved catalytic performance over the established Ru(BINAP)(OAc)2 catalyst, highlighting the impact of anion variation on catalytic asymmetric hydrogenations.
