o-Tolunitrile (1.83 g, 0.0156 mole) and dichlorine monoxide (6.79 g, 0.078 mole) in carbon tetrachloride were heated at 75° for 18.5 hrs in a Carrius tube following the procedure described in Example 6. The reaction mixture was dried (MgSO4) and the solvent removed on a rotary evaporator to give a white crystalline solid (4.09 g, purity by HPLC 85.45%, yield 100%). The product was combined with that of a similar run and recrystallized from cyclohexane to give substantially pure 2-trichloromethylbenzonitrile mp 98.9°-100° C.
