The reactions of β-azolylenamines 1 with sulfonylazides 2 in acetonitrile furnished 1H-4-(azol-5-yl)-1,2,3-triazoles 3 in yields of 52–93 %. β-Benzoylenaminones and β-nitroenamine of type 1 also reacted with tosyl azide to form the same type of products 3, proving the generality and efficiency of the method for the synthesis of N-unsubstituted 1,2,3-triazoles. On the other hand, the reactions of 3-(1-aryl-1
