The Electrochemical Oxidation of [CoII(salen)] in Solvent Mixtures—An Example of a Ladder Scheme with Coupled Electron‐Transfer and Solvent‐Exchange Reactions

Every electron-transfer reaction of a complex process on the electrode, in which individual electron-transfer and chemical reaction steps are coupled in such a way that a cyclic sequence results, was observed separately for the first time in the electrochemical investigation of the CoII complex 1. This is crucial for the detailed description of the catalytic activity of 1, because, as shown here, the redox reactions are strongly dependent on solvent.
