A Study on m-Chloroperbenzoic Acid and Lead Tetraacetate Oxidation of some 1-Aroyl-4,5-dihydro-4,4-dimethyl-5-methylene-1H-pyrazoles

1-Aroyl-4,5-dihydro-5-methylene-1H-pyrazoles 1 are converted upon oxidation with m-chloroperbenzoic acid to the pyrazolones 2.The same aroyl enamides 1 are also oxidized with LTA to form the acetoxy derivatives 7 and 8.The reaction mechanisms are discussed.
