Process for the preparation of nuclear-halogenated benzotrichlorides from the corresponding benzotrifluorides

Nuclear-halogenated benzotrichlorides are prepared in a particularly advantageous manner from the corresponding nuclear-halogenated benzotrifluorides by reacting nuclear-halogenated benzotrifluorides with silicon tetrachloride in the presence of catalytic amounts of aluminium trichloride.
