Hydrogenation of aromatic-substituted olefins using organoruthenium catalyst

摘要: A process is disclosed for the enantioselective hydrogenation of olefins formula ##STR1## where R hydrogen or C1 to C6 linear branched alkyl, Z ##STR2## R' --CN, C(NH)OR" R" --C(O)NH2 ; and Ar phenyl naphthyl unsubstituted substituted with benzoyl benzoyl, alkoxy, halo, carboxylic acid alkyl ester thereof, which comprises contacting said aromatic-substituted olefin a catalytically effective amount ruthenium phosphite complex.
