Abstract
Model α-chloro-β-nitrothieno[2,3-c]pyridazines incorporating N1-(aryl) entity appended with ortho-methoxycarbonyl or trifluoromethyl group were prepared via intramolecular cyclization of their respective N-arylhydrazone precursors. Interaction of these substrates with N′-(p-fluorophenyl)benzothiohydrazide, in the presence of NEt3, furnished the respective 1,3,4-thiadiazoline–pyridazine thiolate hybrids that were S-methylated to produce the corresponding “sulfanyl” derivatives. Their structures were deduced from spectral data, and confirmed by single-crystal X-ray diffraction.
