Catalysis of Metal Ions on Electron Transfer Reactions
The importance of electron transfer processes has been recognized in nearly every subdiscipline of chemistry, i.e., not only inorganic chemistry but also organic and organometallic chemistry. Numerous organic reactions, previously formulated by “movements of electron pairs” are now understood as processes in which an initial electron transfer from a nucleophile (reductant) to an electrophile (oxidant) produces a radical ion pair, which leads to the final products via the follow-up steps involving cleavage and formation of chemical bonds.1–3 The follow-up steps are usually sufficiently rapid to render the initial electron transfer the rate-determining step in an overall irreversible transformation. In such cases, the catalysis on the electron transfer step is essential to control the overall redox reactions.
