Abstract

A palladium-catalyzed disilylation reaction applicable for a variety of non-, α-, or β-substituted and α,β-disubstituted ortho-halophenylethylenes has been developed. This reaction proceeds with high yields and very low catalyst loadings. The two C–Si bonds of the disilylated products could be well-differentiated chemoselectively in the reaction with various electrophiles.
