(Chemical Equation Presented) A series of chroman-6-ol and dihydrobenzofuran-5-ol based compounds with structures similar to vitamin E were examined by cyclic voltammetry and controlled potential electrolysis. The compounds displayed characteristic voltammetric features that enabled their electrochemical behavior to be interpreted in relation to the oxidation mechanism for vitamin E. The electrochemical experiments indicated the presence of several oxidized species: cation radicals, phenoxyl radicals, phenoxonium ions, hemiketals, and p-quinones, whose lifetimes varied depending on the extent of methylation of the aromatic ring (R1, R2, R3) and the nature of substituents R4 and R5.

An α-tocopherol model compound, 2,2,5,7,8-pentamethyl-6-chromanol, reacted with nitric oxide (NO) in the presence of various amounts of oxygen to afford four major products. Distribution of the products was varied depending on the ratio of NO and O2
