Metal ion-coupled electron-transfer reduction of dioxygen

Research output: Contribution to journalReview articlepeer-review

5 Scopus citations


Metal ion-coupled and proton-coupled electron-transfer reactions of dioxygen is described for one-electron, two-electron, and four-electron reduction of dioxygen by one-electron reductants such as ferrocene derivatives as well as by two-electron reductants such as NADH analogs. The catalytic mechanism of the four-electron reduction of dioxygen with cofacial dicobalt porphyrins has been clarified based on the detailed kinetic study and the detection of the intermediate.
