  Catalyst-Free Regioselective N² Arylation of 1,2,3-Triazoles Using Diaryl Iodonium Salts

  摘要：

  The widespread application of 1,2,3-triazoles in pharmaceuticals has resulted in substantial interest toward developing efficient postmodification methods. Whereas there are many postmodification methods available to obtain N-1-substituted 1,2,3-triazoles, developing a selective and convenient protocol to synthesize N-2-aryl-1,2,3-triazoles has been challenging. We report a catalyst-free and regioselective method to access N-2-aryl-1,2,3-triazoles in good to excellent yields (66-97%). This scalable postmodification protocol is effective for a wide range of substrates.

  report a microwave-assisted catalyst and solvent free synthesis of 1,2,3-triazoles through the cycloaddition of trimethylsilylazide and acetylenes. Utilization of a thermally stable azide source, elimination of a metal catalyst, solvent or any additives, and a convenient isolation procedure result in an overall greener approach to access 1,2,3-triazoles on a practical scale with good to excellent yields
