Chirality transfer from optically active allylsilanes to π-allylpalladium complexes

Abstract

The reaction of lithium palladates with the optically active 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 optically active π-allylpalladium complexes containing the η³-(1-methyl-3-phenylallyl) group in high yields.
