General description

3-Chloro-6-phenylpyridazine is an heteroaromatic compound and is investigated by cyclic voltammetry and preparative scale electrolysis in the presence and absence of carbon dioxide. Fluorination of 3-chloro-6-phenylpyridazine with KF under solvent-free conditions in the presence of a phase transfer agent, with or without microwave irradiation is reported.

Application

3-Chloro-6-phenylpyridazine may be used in the synthesis of 6-substituted phenyl-2-(3í-substituted phenylpyridazin-6í-yl)-2,3,4,5-tetrahydropyridazin-3-ones.

A series of 6-substituted phenyl-2-(3'-substituted phenyl pyridazin-6'-yl)-2,3,4,5-tetrahydropyridazin-3-ones has been synthesized. An appropriate aromatic hydrocarbon reacts with succinic anhydride in presence of AlCl3 to yield beta-aroyl propionic acid. The corresponding acid was cyclized with hydrazine hydrate to give 6-(substituted aryl)-2,3,4,5-tetrahydro-3-pyridazinone, which
