An efficient and effective microwave-assisted cross-coupling of terminal alkynes with various aryl chlorides including sterically hindered substrates proceeds fast and generally gives coupled products in very good yields. The conditions were extended successfully to Suzuki coupling, Buchwald-Hartwig amination, and the Heck coupling of aryl chlorides.
