摘要：

The Rh-catalyzed hydrosilylation of butadiynes to chiral allenes in the presence of chiral phosphine ligands is described. For the first time an enantiomeric excess of 22% was achieved using PPM ligand ((2S,4S)-(-)-4-(diphenylphosphino)-2-(diphenylphosphinomethyl)-pyrrolidine). (C) 1999 Elsevier Science Ltd.
