Zusammenfassung:Process for the side-chain chlorination of aromatic compounds completely halogenated in the nucleus, containing methyl groups, and having the general formulas: (I) (II) wherein y=1 or 2, z=0 to 1, x=6-(y+z), n=0 to 8 and k=(8-n) and the methyl groups are, respectively, in the ortho, meta or para position to one another and in the p-position to the oxygen bridge, by thermal chlorination in the liquid phase. The bis-monochloromethyl compounds of formula (II) are novel compounds. The chlorination products are useful as intermediates.
