Abstract

Treatment of aromatic carbaldehyde (diaminomethylene)hydrazones 1 with hot acetic anhydride or benzoyl chloride affords 1,4-diacyl-3-acylamino-5-aryl-4,5-dihydro-1 H-1,2,4-triazoles 2. In contrast, a new type of 0,N-acetal with an 1,2,4-triazole substructure (3) is obtained from 4-pyridine-carbaldehyde (diaminomethylene)hydrazone (li) by using a similar reaction procedure. The structures of all novel compounds were confirmed by spectroscopic data (1H and13C NMR, MS, IR); some representative compounds were also studied by X-ray analysis.
