Toluene → (1,4-Phenylene)bis[(4-methylphenyl)methanone]

Participants

Reaction Steps

To a stirred mixture of 40 g of terephthaloyl chloride and 200 ml of toluene was added in portions 56 g of solid aluminium chloride at such a rate to maintain the reaction temperature at 45°-55°. The thick orange slurry was then heated to 75° for 2 hours, cooled in ice and slowly treated with 200 ml of dilute HCL. The slurry was stirred for 2 hours at room temperature. The solid was collected by filtration, washed with 200 ml of petroleum ether and 2 L of hot water, and dried to constant weight to give 51 g of colorless product, m.p. 178°-187°. This material was used without further purification.
