It is reported herein a novel debenzoylation of diaryl ketones. The effect of the additives, catalysts, and temperature were studied carefully. The results indicate that the yield of this transformation can reach up to 72% under the standard conditions∶ n(ptoluenesulfonic acid)∶n (starting material)=1∶100, n(ethylene glycol)∶n(starting material) =3∶1, toluene, 80 h under reflux. This reaction provides a new method for the debenzoylation of diaryl ketones.
