Features of the use of ClO2 in the oxidation of some alkylphenols

The oxidation of alkylphenols (2,6-dimethylphenol, 3,5-dimethylphenol, 2-iso-bornylphenol, 2-isobornyl-5-methylphenol, 2-isobornyl-6-methylphenol) with chlorine dioxide in water and dichloromethane was studied. The specific features of alkylphenol oxidation under different reaction conditions were revealed. The reaction of alkylated phenols with chlorine dioxide resulted in the formation of quinones and products of oxidative chlorination. The yields of quinones were found to depend on the position of substituents in the aromatic ring of the starting phenols.
