A binary catalyst system of [RuCl2(η6-arene)] 2 and a protic aminothiol (SN) ligand has been found to promote hydrogen transfer between alcohols and carbonyl compounds. The chiral catalyst system with the pipecolinol-derived chiral SN ligand displays excellent stereoselectivity in the asymmetric transfer hydrogenation of aromatic ketones using HCO2H-Et3N. Novel unsymmetrical bis(thiolate)- bridged binuclear complex, which is relevant to the generation of catalytically active species, has been synthesized and structurally characterized.
