Carbon Tetrachloride → 4-Chlorobenzotrichloride

Participants

Reaction Steps

p-Chlorotoluene (1.17 g, 0.0092 mole) and dichlorine monoxide (2.40 g, 0.028 mole) in carbon tetrachloride (35 ml) were mixed and stored in a stoppered bottle at room temperature for 5 days. The initial reaction ws exothermic. The product was dried (MgSO4) and the solvent removed on a rotary evaporator to give 4-chlorotrichloromethylbenzene as a pale yellow oil (2.00 g, purity by HPLC 88.78%; yield 83.9%), containing a small amount of dichlorotrichloromethylbenzene.
