Asymmetric hydrosilylation of 1-arylbutadienes with trichlorosilane in the presence of a chiral ferrocenylphosphine-palladium catalyst gave opticallyactiveallylsilanes, (Z)-1-aryl-1-silyl-2-butenes and their regioisomers.

The reaction of lithium palladates with the opticallyactive allylsilanes, (E)- and(Z)-1-phenyl-1-trimethylsilyl-but-2-ene and (E)-and (z)-1-phenyl-3-trimethylsilylbut-1-ene proceeds stereospecifically [anti attack of palladium(II) with respect to the leaving silyl group] to give opticallyactiveπ-allylpalladiumcomplexes containing the η3-(1-methyl-3-phenylallyl) group in high yields.
