Abstract
THE detection by electron spin resonance of the 2,6,-di-t-butyl-4-methylphenoxy radical during the oxidation of the corresponding phenol with lead dioxide has been reported recently1. The purpose of this communication is to report a similar investigation of the free radicals formed during the oxidation of solutions of the hindered phenols 2,6,-di-t-butyl-4-R-phenol [where R ≡ methyl (I); ethyl (II); and t-butyl (III)] with an alkaline solution of potassium ferricyanide.
