Cuprous oxide on charcoal (Cu2O/C), the preparation of which is described for the first time, catalyzes the formation of 1,4-disubstituted 1,2,3-triazoles from organic azides and terminalalkynes in good to excellent yields (69-94%). These disubstituted triazoles can be equally efficiently generated in a one-pot process from alkyl bromides, sodiumazide, and terminal acetylenes in 50% aqueous isopropanol
