The electrochemical oxidation of x-tocopherol (vitamin E)(x-TOH) occurs in a -2e-/-H+ process to form the phenoxonium cation (x-TO+) which survices for several hours at room temperature in ultra-dry organic solvents such as acetonitrile and dicloromethane. As the water content of the organic solvent...
