Abstract

When the hydrazone of an unsymmetrical dibenzalacetone rearranges to the isomeric pyrazoline two products are theoretically possible. The identification of these products is somewhat difficult. In previous work in this Laboratory¹ the pyrazolines have been oxidized by aqueous alkaline permanganate solution and the substituted pyrazole and benzoic acids, respectively, separated and identified. The yields are small due to the fact that the permanganate is known to degrade some members of both these groups further.² In the present work the ketones used contained substituted vanillal residues, and the oxidation was done in pyridine solution. The yields were much higher than those previously obtained.
