The three-component reactions of enaminones, tosylhydrazine and primary amines enabled a regioselective construction of 1,5-disubstituted 1,2,3-triazoles via cascade dual C-N bond formation, N-N bond formation and an acyl migration-based C-C bond formation. This metal- and azide-free method proceeds in the presence of only molecular iodine.
