A method for enantioselective hydrogenation of cyclic imines with gaseous hydrogen has been developed. Easily accessible Noyori-Ikariya Ru(II) and Rh(III) complexes can be used directly without an inert atmosphere. Substrate activation has been achie

The use of nonprotic solvents (e.g., dichloromethane, toluene) increases the enantioselectivity of the asymmetric hydrogenation of olefins with chiral [Rh(Me-BPE)(cod)]OTf [Me-BPE=1,2-bis(2,5-dimethylphospholano)ethane; cod=1,5-cyclooctadiene; OTf=tr

Only four types of dimeric precursors [RuCl2(η6-arene)]2 for the synthesis of Noyori’s half sandwich diamine catalysts [RuCl(TsDPEN)(η6-arene)] are commercially available, yet so far no study has tried to systematically evaluate how these systems
