Reactivity of pyridazines 1, 2, 3, 16 towards ethoxycarbonylradical (generated by redox decomposition of oxyhydroperoxyde of ethylpyruvate) was studied.Application of this type of homolytic substitution for synthesis of hitherto not accessible pyridazine carboxylic acid esters 6, 8, 9, 12, 13, 14, 15, 17 is demonstrated.In addition improved synthesis of diethyl 4,5-pyridazinedicarboxylate (5) is proposed.
