Microwave-enhanced highly efficient protocol for the synthesis of polyfunctional pyridazines beginning from 3,6-dichloropyridazine in environmentally benign ionic liquids have been developed. The products obtained were 3-amino-6-chloropyridazine, 3,6-diaminopyridazine, and 3-chloro-6- methoxypyridazine. These derivatives were then be converted to a variety of polyfunctional pyridazine derivatives. The ionic liquids used were 1-n-butyl-3-methylimidazolium hydroxide/tetrafluoroborate/hexafluorophosphate and 1,3-di-n-butylimidazolium hydroxide. This powerful strategy is less time-consuming green methodology. The ionic liquid employed may be recovered and recycled.

Compounds 1-3 were obtained in the reaction of 3,6-dichloro-pyridazines with phenylacetonitriles in the biphasic system - DMSO/50% NaOH. The chlorine atom was replaced with cycloalkylamino (4-13) and hydrazinyl (23, 24) moiety. These last compounds were condensed with aldehydes (25-34). Pyridazynylphenylacetonitriles were converted into amides 14-18 and thioamides 19-22. In compounds 2, 3 the chlorine atom was replaced with thiophenyl (37, 38) and in compound 1 with thioethyl and thiophenyl (35, 36) functional groups. In the reactions of compounds 1, 2 with ammonium polysulfide thioamides with thiol group (39, 40) and chlorine atom (41, 42) were obtained. Compounds 1-17, 19-43 were screened for antibacterial and fungicidal activities.
