diazo group transfer reaction with p-tosyl azide. It was found that alkylation of sodium 1-aryl- and 1-arylmethyleneamino-1,2,3-triazol-5-olates 7, 4 with methyl iodide, benzyl chloride or substituted phenacyl bromides results in 3-alkyltriazol-3-ium-5-olates 8, 9 that are compounds of mesoionic structure. In contrast, alkylation of 1-arylsulfonyl-substituted triazoles 6 with methyl iodide leads to
