Novel chiral phosphorus compounds are described, which have the formula <IMAGE> in which R denotes lower alkyl, R<1> denotes phenyl and R<2> and R<3> denote hydrogen or lower alkoxy. In the form of complexes with a metal from group VIII, the compounds of the formula I serve as catalysts for asymmetric hydrogenations and for enantioselective hydrogen shifts in prochiral allylic systems. |
