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 ...
