    • Our preliminary investigation indicated that the reactions with thiazoles and imidazoles were unsuccessful. Given that the formation of the diyne side product was also inhibited, the strong coordination nature of sulfur and nitrogen atoms of these azoles would cause the deactivation of copper complexes
