Oxidation of Bis-aroylhydrazones of 3,3-Dimethylpentane-2,4-dione and Thermal Decomposition of the Oxidation Products (1)

Oxidation of the title bis-aroylhydrazones 2 with lead tetraacetate gives 1-aroyl-5-aroylazo-3,4,4,5-tetramethyl-2-pyrazolines 6 in good yields.The aroylazopyrazolines 6 decompouse by refluxing in chloroform of ethanol solution to 1-aroyl-5-hydroxy-3,4,4,5-tetramethyl-2-pyrazolines 3, 1-aroyl-5-methylene-3,4,4-trimethyl-2-pyrazoles 10 and 1-aroyl-3,4,4,5-tetramethyl-2-pyrazolines 11.The spectral data of the, prepared compounds, as well as the reaction mechanisms are discussed.
