One-pot preparation of 2,5-dichloro-4'-phenyloxybenzophenone

Davis, Matthew C.,Groshens, Thomas J.

, p. 255 - 261 (2011)

Friedel-Crafts-type acylation of phenyl ether with 2,5-dichlorobenzoic acid could be accomplished in a single step using trifluoroacetic anhydride and phosphoric acid. The method gave a greater yield (78%) than the conventional two-step process (71%) of acid chloride generation followed by aluminum trichloride-mediated acylation.
