Abstract
δ-Tocopherol was reacted with an alkylperoxyl radical at 37°C in benzene. 2, 2'-Azobis(2, 4-dimethylvaleronitrile) was used to generate the alkylperoxyl radical. The reaction products of δ-tocopherol were isolated and characterized. There were δ-tocored, four stereoisomers of 8a(1-cyano-l, 3-dimethyl)butylperoxy-δ-tocopherone, a mixture of four stereoisomers of 8a-(1-cyano1, 3-dimethyl)butylperoxy-5-(δ-tocopheroxy)-δ-tocopherone, 5-(δ-tocopheroxy)-δ-tocopherol, a mixture of four stereoisomers of 8a-(1-cyano-l, 3-dimethyl)butylperoxy-5-[(5-(δ-tocopheroxy)-δ-tocopheroxy]-δ-tocopherone, and 5-[(5-(δ-tocopheroxy)-δ-tocopheroxy]-δ-tocopherol. From the reaction products of δ-tocopherol and its dimer, a possible mechanism for the reaction of δ-tocopherol with peroxyl radicals was discussed.
