Abstract
Disclosed is a method of making trichloromethoxybenzene. A mixture is prepared of anisole and a source of chlorine free radicals, such as chlorine or sulfuryl chloride. The reaction is performed in a solvent, which can be either benzotrifluoride, orthochlorobenzotrifluoride, metachlorobenzotrifluoride, parachlorobenzotrifluoride, or dichlorobenzotrifluoride. The mixture is exposed to actinic radiation, such as ultraviolet light, which generates the chlorine free radicals.
