Starting material ratios as low as 1.1/1.3/1 (moles of AlCl3 :1,4-dichlorobenzene:benzoyl chloride) have been found sufficient to produce 2,5-dichlorobenzophenone in about 50% yield under the conditions provided by the present invention; the same ratio of starting materials has been found to give a 64% yield of 2,5-dichlorobenzophenone if the benzoyl chloride is added slowly to a mixture of AlCl3, 1,4-dichlorobenzene and a small amount of benzoyl chloride.
