Abstract
Abstract The homolytic substitution of protonated 3-chloro-6-methylpyridazine 1a , followed by hydrolysis with AcOH affords 4- or 4,5-functionalized pyridazinones 3a-c . Less reactivity is found for 3-chloro-6-phenylpyridazine 1b . Hypotheses about these different behaviour patterns are proposed and discussed
