The Rh-catalyzed hydrosilylation of butadiynes to chiral allenes in the presence of chiral phosphine ligands is d~scribed. For the first time an enantiomeric excess of 22% was achieved using PPM ligand ((2S,4S)-(-)-4-(diphenylphosphino)-2-(diphenylphosphinomethyl)-pyrrolidine).

swmnary : Optically active norbornyl and l-phenylethyl alcohols and bromides were obtained, res- pectively, from norbornyl-and l-phenylethylpentafluorosilicates which were prepared by asymmetric hydrosilylation of norbornene and styrene with trichlorosilane catalyzed by a chiral ferrocenylphosphine-
