An efficient new method has been developed to synthesize N²-alkyl 1,2,3-triazole products by toluenesulfonic acid (TsOH) catalyzed addition of N¹-Ts substituted 1,2,3-triazoles to olefins. The reactions of monosubstituted and unsubstituted triazole substrates with various olefins, including vinyl esters, are explored.
