Moist kaolin catalyses the regioselective and high-yielding chlorination and bromination of C6H5OR (R = C1-C8 alkyl. Bu1, allyl, cyclohexyl, benzyl) to 4-XC6H4OR (X = Cl and Br, respectively) with NaCl02 and Mn(acac)3 in CH2Cl2 in the absence and presence of NaBr, respectively, under mild and neutral conditions.

A solid-liquid biphasic system (dichloromethane and chromatographic neutral alumina) has been tested for the aromatic chlorination of various alkyl aryl ethers using a reagent combination of sodium chlorite and manganese(III) acetylacetonate catalyst. Efficient incorporation of a chlorine atom into the benzene ring with high para-selectivity results. This catalytic system is also applicable to the regiocontrolled chlorination of polyether substrates.
