A series of pyridazino[3,2-c]1,2,4-triazoles were synthesized from hydrazides and 3-aryl-6- chloropyridazines (3a3d), which were obtained from substituted benzene and succinic anhydride by Friedel-Crafts reaction, cyclization with hydrazine hydrate, dehydrogenation and chloro-substitution. Their structures were established by elemental analysis, IR, 1H NMR and MS spectra.

Key words: pyridazine, 1,2,4-triazole, pyridazinone
