ω-Halogen-ω-(phenylhydrazono)acetophenones (6a-l) with electron-withdrawing substituents in the acetophenone moiety react with 3-amino-4H-1,2,4-triazole (2) to form monocyclic substitution products, ω-(3-amino-1,2,4-triazol-4-yl)-ω-(phenylhydrazono)acetophenones (7a-l).The latter yield bicyclic 3-aroyl-1-aryl-1H-triazolo-1,2,4-triazoles (8a-l).With 5 amino-3-methyl-1H-pyrazole (14) or 5-aminotetrazole (19) instead of 2, the reaction takes another course in each case.The differing reaction pathways are discussed by means of X-ray analysis and molecular modelling.
