โœฆ Synopsis


Asymmetric hydrosilylation of l-arylbutadienes with trichlorosilane in the presence of a chiral ferrocenylphosphine-palladium catalyst gave optically active allylsilanes, (z)-laryl-1-silyl-Z-butenes and their regioisomers.

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).
