Procedure

22 g (0.2 mole) of hydroquinone were dissolved in 60 ml of dichloroethane and 26.8 g (0.2 mole) of anhydrous aluminum chloride were added to the solution. To the obtained complex 30.8 g (0.2 mole) of phenyl-acetyl chloride in 30 ml of dichloroethane were added. Further the procedure of Example 1 was followed. 10.1 g of 2,5-dihydroxy-phenyl-benzyl-ketone were obtained, m.p.: 118°-120° C.
