α-Tocopherol was reacted with an alkylperoxyi radical at 37℃ in benzene. 2,2'-Azobis(2,4-dimethylvaleronitrile) was used to generate the alkylperoxyi radicals. The reaction products of α-tocopherol were isolated by reverse-phase and normal-phase high performance liquid chromatography, and their structures were characterized. They were four stereoisomers of 8a-(1-cyano-1,3-dimethyl)butylperoxy-α-tocopherone, spirodiene dimer and two geometrical isomers of the trimer. When α-tocopherol at a low concentration was reacted with AMVN, the major products were 8a-alkylperoxy-α-tocopherones. On the other hand, the products of the alkylperoxyl radical with α-tocopherol at a high concentration were spirodiene dimer and trimer in addition to the 8a-alkylperoxy-α-tocopherones.
