Abstract
We report a simple and quick synthetic method of some new Aza-Wittig reagents in anhydrous acetonitrile under microwave irradiation. 1-Substituted aryl-4-ethoxycarbonyl-5-[(triphenylphosphoranylidene)amino]-1, 2, 3-triazoles can be obtained within three minutes by microwave irradiation to the mixture of 1-substituted aryl-4-ethoxycarbonyl-5-amino-1,2,3-triazoles, triphenylphosphine, hexachloroethane and triethylamine. The products were characteried by IR, NMR, MS methods and elemental analysis.
