Procedure

To a mechanically stirred, 600 mL autoclave is added 1 mole of isophthaloyl dichloride, 10 moles of benzene and 2% iron chloride, based on the amount of isophthaloyl dichloride. The reactor is closed and the temperature of the reaction zone is elevated to 200° C. The reaction goes to completion in approximately 4 to5 hours with a quantitative yield of 1,3-phenylene-bis(phenyl methanone). The maximum pressure experienced during the reaction was 300 psig.
