3,6-Dichloro-4-pyridazinecarbonyl chloride (4) reacts with primary amines to yield the N-containing fused heterocyclic compounds 2, 8, and 9a, b. 4 forms the pyridazino-oxadiazepines 7a-d with the in situ generated hydroxyguanidines 6a-d.The diazocinedione 1 is obtained by reaction of 3,6-dichloro-4-pyridazinecarboxamide (3) with anthranilic acid methyl ester.
