A major product of the reaction between α‐tocopherol and t ‐butyl hydroperoxide in chloroform is 5‐ethoxymethyl‐7,8‐dimethyl tocol, the source of the ethoxy group being the ethanol that is used to stabilize the chloroform. Two new products of this oxidation have now been identified as 2‐(3′‐hydroxy‐3′,7′,11′,15′‐tetramethylhexadecyl), 3‐ethoxymethyl‐5,6‐dimethylbenzo‐1,4‐quinone and 5‐ethoxycarbonyl‐7,8‐dimethyl tocol. These two compounds and another major product, 5‐formyl‐7,8‐dimethyl tocol appear to be formed by further oxidation of 5‐ethoxymethyl‐7,8‐dimethyl tocol.
