Methyl Carbonium Ion Migration during the Reaction of 4-Chloro-5-methoxyl-3(2H)-pyridazinone with Trifluoroethylation Agents
To synthesize 4-chloro-5-methoxy-2-(β-trifluoroethyl)-3(2H)-pyridazinone (4), the reactions of 4-chloro-5-methoxy-3(2H)-pyridazinone (5) with RCH(2)CF(3) (R = I, TsO, MsO, TfO) in different solvents were studied. It was found that methyl group migration took place during this reaction. An oxonium sa...
