Palladium-catalysed borylsilylation of alkynes and borylsilylative carbocyclization of diynes and an enyne compound

Abstract

Addition reactions or addition–carbocyclization reactions of a borylsilane with alkynes, α,ω-diynes or an enyne compound proceed efficiently in the presence of palladium catalysts, P(OCH 2 ) 3 CEt being the ligand of choice.
