Procedure

0.5 g of potassium chloride and 10 g of difluoromethoxybenzene in 100 ml of 1,3-bistrifluoromethylbenzene were introduced as the initial charge, and chlorine was then introduced at 100° C. with UV irradiation. In the course of an hour, another 20 g of difluoromethoxybenzene were metered in. After chlorine uptake was complete, the reaction mixture was purged with nitrogen and subsequently distilled. 35.5 g of chlorodifluoromethoxybenzene were isolated (boiling point 144° C., refractive index nD20 1.4479).
