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 RCH2CF3 (R = I, TsO, MsO, TfO) in different solvents were studied. It was found that methyl group migration took place during this reaction. An oxonium salt 9 was suggested as the active intermediate for the formation of the byproduct 4-chloro-5-methoxy-2-methyl-3(2H)-pyridazinone (7) and4-chloro-2-methyl-5-(β-trifluoroethoxy)-3(2)-pyridazinone(8).
