Procedure

A mixture containing 131.5 g (1.0 mole), of trichloroethylene, 80.5 (0.5 mole) of 3,4-dichlorotoluene and 5 g. of aluminum chloride was stirred and heated at reflux for 2 hours. The reaction mixture was then washed with concentrated HCl, then with water until neutral, dried and distilled. 42.7 grams of product was collected, having a boiling point of 97°-102°C at 0.5 mm Hg pressure.
