Abstract A series of 1-tosyl-substituted 4-arylcarbamoyl-1, 2, 3-triazol-2-olates, which can undergo rearrangement to isomeric 1-aryl-4-tosylcarbamoyl-1, 2, 3-triazol-5-olates and N- tosyl-N'-aryldiazomalonimidolates, were synthesized. An equilibrium between these compounds is observed in solutions in DMSO. The introduction of an electron-withdrawing substituent into the aryl residue increases the stability of the 1-tosyl-1, 2, 3-triazoles but ...
