n intensive investigation of the reaction of hexamethylenetetramine with dibenzoylmethane under varying conditions in methanol, ethanol and their mixtures with water, and also in water alone has been carried out The effect of 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,gamma-tetrabenzoylpropane in the theoretical yield, hitherto, not reported in the literature. Methylene-bis-dibenzoylmethane thus obtained turned out to be tautomeric in nature. It has not been reported in the literature so far. Its tautomeric nature has been established and is being reported for the first time.
