The electrochemical oxidation of α-sulfonylcarbanions is shown to involve a coupling reaction between the electrogenerated radical and the parent anionic species, both on preparative and kinetic grounds. Two routes compete for the further evolution of the ensuing anion radical: (i) a two step desulfonylation leading to the dimeric olefin, the product of an overall catalytic process, (ii) or further
