Cathodic oxidation of sulfoxides to sulfones using a tungstate/pertungstate redox mediator

Article abstract of DOI:10.1246/cl.1997.387

A new cathodic oxidation system for the oxidation of sulfoxides was developed. The system involves the cathodic reduction of dioxygen to hydrogen peroxide which oxidizes tungstate to pertungstate in the solution, and sulfoxides arc oxidized to the corresponding sulfones with the resulting tungstate/ pertungstate redox mediator in high cfficncy and selectivity.
