Gas-phase pyrolysis of N-arylidine-N′-pyrimidin-2-yl-hydrazine derivatives 1a, 1b, 1c, 1d, 1e gave the corresponding arylnitriles 2a, 2b, 2c, 2d, 2e, 2-aminopyrimidine 3, 3-phenyl-1,2,4-triazolo[4,3-a]pyrimidines 4, 2-phenyl-1,2,4-triazolo[1,5-a]pyrimidines 5, 2,4,5-triphenyl-1H-imidazole 6, and 2,3-diphenylquinoline 7. The analyses of the reaction products are reported and used to elucidate the mechanism of the pyrolytic process.

A series of 1,2,4-triazoles have been prepared by oxidative intramolecular cyclization of heterocyclic hydrazones with copper dichloride. General applicability of this simple transformation was confirmed by the synthesis of moderate to high yields of 1,2,
