Popis:	Cu-catalyzed cross-coupling of 5-stibano-1,2,3-triazoles with bromoalkynes is described. The reaction of 5-stibanotriazoles with bromoalkynes under aerobic conditions in DMF, using a combination of 10 mol% of Cu2O and 1,10-phenanthroline, produced a variety of 5-alkynyltriazoles in moderate-to-excellent yields. This reaction is the first example of Cu-catalyzed C(Ar)–C(sp) bond formation using trivalent organoantimony compounds.
