Copper-catalyzed cross- and carbonylative coupling reactions have been achieved in the reaction of a variety of alkynyliodonium salts with arylboronic acids and organostannanes under the mild reaction conditions in high yield. Our investigation shows that the alkynylidonium tetrafluoroborates are more efficient than those of triflates and tosylates.
