The electrochemical oxidation of phenols and their alkyl ethers not containing strong electron-withdrawing substituents in fluorosulfonic acid takes place in the form of the benzenonium ions and is irreversible in character.With the introduction of substituents of the -M type into the benzene ring the oxidation process affects the unprotonated molecules to a first approximation and in many cases goes reversibly to the radical-cations.Comparison of the oxidation potentials of the substrates in acetonitrile and fluorosulfonic acid made it possible to reveal certain characteristics of the fine structure of these radical-cations, which is determined by the ability of the latter to interact with the medium.Heterocyclic cations whose oxidation potentials in acetonitrile lie beyond the limit of the discharge of the supporting electrolyte can be oxidized in fluorosulfonic acid.Cations of the quinolinium, isoquinolinium, acridinium, acridizinium, imidazolium, and other series, which have irreversible many-electron waves in acetonitrile, give well-defined reversible peaks for oxidation to the corresponding radical-dications in fluorosulfonic acid.In phenyl- and benzyl-substituted cations the substituents and not the positively charged heterocycle itself can undergo oxidation.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Related Products of 6640-47-7. In my other articles, you can also check out more blogs about 6640-47-7
