Systematic synthesis of a number of new phenolic compounds with structures similar to vitamin E led to the identification of several sterically hindered compounds that when electrochemically oxidised in acetonitrile in a -2e-/-H+ process formed phenoxonium diamagnetic cations that were resistant to hydrolysis reactions. The reactivity of the phenoxonium ions was ascertained by performing cyclic voltammetric scans during the addition of carefully controlled quantities of water into acetonitrile solutions, with the data modelled using digital simulation techniques.

On photolysis with tungsten light, the acyl derivatives of N-hydroxy-2-thiopyridone afford carbon radicals which readily add to quinones.In the case of benzoquinone radical addition is followed by 2-thiopyridyl transfer to afford adducts of type 4.Two different procedures were developed for the conversion of type 4 compounds into hindered quinones of type 7.
