Ynamides were prepared through an efficient copper-catalyzed coupling reaction. In the presence of copper iodide, 1,10-phenanthroline, and Cs2CO3, the coupling reaction of 1,2-dibromo-1-styrenes with sulfonamides proceeded smoothly and generated the corresponding products with excellent isolated yields.
