Electrochemical Oxidation of Olefins Using N-Hydroxyphthalimide as a Mediator

Abstract

Electrochemical oxidation of olefins using N-hydroxyphthalimide as a mediator was studied. Allylic methylene and allylic methine groups were oxidized to give the corresponding enones, while allylic methyl groups were not readily oxidized except for those of 2, 3-dimethyl-2-butene. The product distribution was similar to that observed in free radical autoxidation of olefins. A possible mechanism of the oxidation is proposed.
