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.
On divulgue une méthode de fabrication de trichlorométhoxybenzène. Un mélange est préparé avec de l'anisole et une source de radicaux de chlore libres, comme du chlore ou du chlorure de sulfuryle. La réaction est réalisée dans un solvant, qui peut être soit du benzotrifluorure, de l'orthochlorobenzotrifluorure, du métachlorobenzotrifluorure, du parachlorobenzotrifluorure ou du dichlorobenzotrifluorure. Le mélange est exposé à un rayonnement actinique, comme la lumière ultraviolette, qui génère des radicaux de chlore libres.
