Palladium-catalysed reductive addition of aryl iodides to aryl and alkylethynylsilanes: A stereo and regioselective route to functionalized 2,2-disubstituted vinylsilanes

Abstract

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