1,3-Enynes were easily prepared from coupling between vinylhalides and alkynes or domino coupling of vinylhalides in the presence of copper iodide. It is noteworthy that the double-bond geometry of the vinylhalides was retained during the reaction. This ligand-free protocol is potentially useful and practical.
