4-Alkyl or aryl-3,5-diphenyl-4H-1,2,4-triazoles, 3-phenyl-1,2,4-triazolo[4,3-a]pyridine, and -pyrimidine are obtained by the title reactions. The reaction may proceed via the nucleophilic attack of amidine or imidate on the imidoyl carbon of hydrazonoyl chloride and the subsequent intramolecular cyclization of the intermediate formed in the initial step, with the removal of the amino or alkoxyl and phenylsulfonyl groups.

Despite steric hindrances created by the bulky substituent on the nitrogen atom, halogenation of 2,5-dialkyl-N-[arylsulfonylimino(phenyl)methyl]-1,4-benzoquinone monoimines fairly readily gives their derivatives having two halogen atoms in the quinoid ring.
