Organic reactions in aqueous solution - part-X: Effect of sonication on the reaction of hexamethylenetetramine with dibenzoylmethane in the formationof alpha,alpha,gamma,gamma-tetrabenzoylpropane

An intensive investigation of the reaction of hexamethylenetetramine with d ibenzoylmethane under varying conditions in methanol, ethanol and their mix tures with water, and also in water alone has been carried out The effect o f sonication an these reactions has also been studied The study has led to the development of a simple method for the synthesis of alpha,alpha,gamma,g amma-tetrabenzoylpropane in the theoretical yield, hitherto, not reported i n the literature. Methylene-bis-dibenzoylmethane thus obtained turned out t o be tautomeric in nature. It has not been reported in the literature so fa r. Its tautomeric nature has been established and is being reported for the first time.
