CONVERSION OF DISILANES TO FUNCTIONAL MONOSILANES. XIII. THE PALLADIUM CATALYZED REDUCTIVE COUPLING OF BENZYLIDENE DICHLORIDES AND BENZYLIDYNE TRICHLORIDES USING DISILANES AS REDUCING AGENTS.

The reaction of benzylidene dichlorides or benzylidene trichlorides with 1,2-dichloro-1,1,2,2-tetramethyl-disilane or hexamethyldisilane proceeded smoothly in the presence of a catalytic amount of Pd(PPh//3)//4 to give (E)-stilbenes or (E)- and (Z)- alpha beta -dichlorostilbenes in high yields, respectively. Also, in the presence of the palladium (0) catalyst, alpha , alpha -dichlorobenzyltrimethylsilanes reacted with hexamethyldisilane yielding (E)- alpha , beta -bis(trimethylsilyl)stilbenes in quantitative yield.
