✦ Synopsis

Chiral catio@c )and neutral Rh complexes RhX(bichep)(nbd) (X=CI,'C104; nbd=norbornadiene;bichep=2~2'-bis(dicyclohexylphosphino)-6,6'-dimethyl-l, I'-biphenyl) are highly active and excellent Catalysts for enantioselective hydrogenation of prochiral olefins and ketones under mild reaction conditions.
