摘要：

In the present communication we wish to report a copper-free Sonogashira reaction catalyzed by gold-supported catalysts under microwave irradiation. Aryl and alkyl acetylenes were used and good yields were obtained with short reaction times when DMF was used as solvent. Three different supported gold catalysts were used and Au/SiO2 gave the best result for both aryl and alkyl acetylenes.
