TRANSITION-METAL CATALYZED SILYLZINCATION AND SILYLALUMINATION OF ACETYLENIC COMPOUNDS
Dialkyl(dimethylphenylsilyl)zinclithium and trialkyl(dimethylphenylsilyl)aluminiumlithium add effectively to internal acetylenes as well as terminal ones in the presence of transition-metal catalysts to provide vinylsilanes with high stereo- and regiosele
