Procedure

To 3.8 (0.01 mole) 4,4"-dibromoterphenyl in 200 ml nitrobenzene is added 0.86 g (0.011 mole) acetyl chloride and 1.46 g (0.011 mole) aluminum trichloride. The mixture is heated to 80° C. under inert atmosphere for three hours. The mixture is cooled to room temperature and washed with 1 m HCl. The organic layer of 2'-acetyl-4,4"-dibromoterphenyl is separated and the solids filtered and washed with several portions of ethanol, and dried.
