Vinyltrialkoxysilanes are indispensable for organicsynthesis, particularly cross-coupling reactions. Hydrosilylation of alkynes inevitably yields α- and β-isomers of vinyltrialkoxysilanes even with complex ligands and catalysts, limiting its usage in organicsynthesis. We report the synthesis of α-vinyltrialkoxysilanes via cross-electrophile C(sp2)–C(sp2) coupling of bromoalkenes. The method is quite
