A Convenient Biphasic System (Alumina—Dichloromethane) for the Efficient Aromatic Monochlorination of Alkyl Phenyl Ethers with Sodium Chlorite in the Catalytic Presence of Manganese(III) Salt.

Abstract A combination of sodium chlorite, (salen)manganese(III) catalyst, and chromatographic neutral alumina in dichloromethane can be successfully utilized for the aromatic monochlorination of a variety of alkyl phenyl ethers in excellent to quantitative yields under mild and anhydrous conditions.
