Abstract:

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.

Key words: Brönsted acid catalysis, N2-alkyl 1,2,3-triazole, N1-toluenesulfonyl triazole, Olefin reaction, High N2-selectivity
