Abstract

A variety of terminal arylacetylenes have been conveniently synthesised in good to high yields via Sonogashira coupling of aryl iodides with (trimethylsilyl) acetylene catalysed by a MCM-41-supported bidentate phosphine palladium (0) complex, followed by desilylation. The polymeric palladium catalyst can be reused many times without any decrease in activity.
