Reaction Steps
3-Fluoro-4,6-dichlorotoluene is prepared with reduced formation of 3-fluoro-2,6-dichlorotoluene by chlorinating 3-fluorotoluene in the presence of a catalyst system to give a mixture containing 3-fluoro-6-chlorotoluene and 3-fluoro-4-chlorotoluene and chlorinating this in the presence of another catalyst system to give 3-fluoro-4,6-dichlorotoluene.
