An efficient synthesis of 2-aryl 1,2,3-triazoles based on an intramolecular N–N bond formation is described. Selective activation of bis-hydrazone at the dimethylamino hydrazone group with MeI forms a mono-hydrazonium species. Treatment of the hydrazonium

The oxidation of N-aminophthalimide (1) with lead tetraacetate in the presence of the phenylazoalkenes 2 afforded 2-phenylazo-1-(N-phthalimido)aziridines 3 or 2-phenyl[1,2,3]-triazoles 7, as well as phthalimide (4). The reaction of 2-phenylazo-1-propene (2d) produced 5-methyl-2-phenyl-[1,2,3]triazole (7d) and N-[2-(phenylhydrazono)propylidene-amino]phthalimide (8d). The cyclic azoalkene 3,3,5-trimethyl-3H-pyrazole (11) gave a mixture of (Z)-3,3,5-trimethyl-1-[N-(phthalimido)amino]-3H-pyrazol-1-ium-2N-ide [(Z)-12] together with the regioisomers (E)- and (Z)-3,3,5-trimethyl-1-[N-(phthalimido)amino]-3H-pyrazol-2-ium-1N-ides [(E)- and (Z)-13].

Pyrazole N-oxides and 1,2,3-triazole-N-oxides can be C-silylated at ring exocyclic α-positions in high yields in a one-pot procedure by treatment with trimethylsilyl triflate, trimethylsilyl iodide or tert-butyldimethylsilyl triflate in the presence of 1,
