摘要
A variety of terminal arylacetylenes have been conveniently synthesized in good to high yields via Sonogashira coupling of aryl iodides with (trimethylsilyl) acetylene catalyzed by MCM-41-supported mercapto palladium(0) complex, followed by desilylation under mild conditions. This polymeric palladium catalyst can be reused many times without any decrease in activity.
