• The reaction of benzylidene dichlorides or benzylidyne trichlorides with 1,2-dichloro-1,1,2,2-tetramethyldisilane or hexamethyldisilane proceeded smoothly in the presence of acatalytic amount of Pd(PPh<SUB>3</SUB>)<SUB>4</SUB> to give (<I>E</I>)-stilbenes or (<I>E</I>)- and (<I>Z</I>)-α,β-dichlorostilbenes in high yields, respectively. Also, in the presence of the palladium(0) catalyst, α,α-dichlorobenzyltrimethylsilanes reacted with hexamethyldisilane yielding (<I>E</I>)-α,β-bis(trimethylsilyl)stilbenes in quantitative yield.
