Aryl and alkylethynylsilanes are converted into 2,2-disubstituted vinylsilanes containing various common functional groups in the presence of aryliodides, a palladium catalyst, formic acid, and a tertiary or secondary amine with high stereoselectivity and good regioselectivity.

Representative vinyl and aryl bromides are cross-coupled, under basic conditions, to Z-alpha-trimethylsilylvinylboranes with tetrakis(triphenylphosphine)palladium(O) catalyst to provide the corresponding silylated styrenes and 1,3-dienes (40-60%, > 98% Z).
