Abstract
A palladium-catalysed Hiyama cross-coupling reaction of alkynyl halides with aryltrialkoxysilanes has been developed. Catalysed by bis(dibenzylideneacetone)palladium and in the presence of silver fluoride and potassium bicarbonate, a variety of alkynyl halides (I, Br and Cl), whether electron-deficient or electron-rich, underwent the cross-coupling reaction with aryltrialkoxysilanes at room temperature to afford the corresponding alkynes in moderate to good yields.
