Reaktionsschritte

70.3 g of benzoyl chloride was added into the mixture of aluminium chloride (93.3 g) and 1,2-dichloro benzene (14.7 g) using 500 mL three necked flask, then reaction was carried out for 12 hrs. at 120° C. The reaction mixture was poured into 1000 g of ice water in a beaker (5000 mL), and further, 1000 g of toluene was added. The toluene layer was washed by 1000 g of water three times. After condensing the toluene layer under reduced pressure, 87 g of 3,4-dichlorobenzophenone was obtained (yield 69%)
