Direct coupling reaction of benzo[b]thiophene and electron-rich aryl bromides was achieved under Pd2(dba)3/SPhos catalysis in the presence of NaOt-Bu. The reaction system was applied for the installation of 2-(methylthio)phenyl group onto thiophene-fused polyaromatic molecules, demonstrating facile synthesis of precursors for thienoacene derivatives.

A variety of terminal arylacetylenes have been conveniently synthesised in good to high yields by Stille coupling of aryl halides with ethynyltributylstannane catalysed by a MCM-41-supported bidentate phosphine palladium(O) complex in an aqueous medium and under air. Our system not only avoids the requirement for water-free and oxygen-free conditions, but also solves the basic problem of palladium catalyst reuse.
