Abstract
Dibenzoylmethanes are easily prepared in two steps starting from acetophenones, phenol and benzoyl chlorides. The phenyl benzoate is obtained by condensation of benzoyl chloride with phenol in a classical way. Stirring of the phenyl benzoate and acetophenone in DMSO with powdered sodium hydroxide during a few minutes gave the dibenzoylmethanes in yields depending on substituents on the phenyl rings.
