THE OXIDATION OF PHENOLS: II. THE OXIDATION OF 2,4-DI-t-BUTYLPHENOL WITH PEROXY RADICALS

Abstract

Ten products from the oxidation of 2,4-di-t-butylpheuol with t-butyl peroxy radicals have been identified. They can be subdivided into three groups, depending on the type of radical–radical coupling reaction by which they are produced or in which their precursors are formed: (i) phenoxy–peroxy coupling, (ii) phenoxy–phenoxy coupling at the 6 positions, and (iii) phenoxy–phenoxy coupling through the oxygen atom of one radical and the 6 position of the second radical. Products resulting from still other phenoxy–phenoxy coupling reactions are undoubtedly formed in minor amounts.
