Abstract

The OO bond cleavage of peroxide ligands such as hydro-peroxide and alkylperoxide within metalloenzymes has been extensively investigated because this process constitutes the key step of dioxygen activation and cellular respiration in all forms of aerobic organisms. Herein, we have provided mechanistic insights into the OO bond cleavage of iron-(hydro/alkyl)peroxo complexes that was promoted by endogenous and exogenous factors such as spin-state, axial ligand, and electron donors. It has been shown that these factors can effectively direct the OO bond cleaving pathways (e.g., FeO bond cleavage vs OO bond cleavage or homolysis vs heterolysis). These results support that the peroxide bond cleavage process might proceed via diverse pathways under biological reaction conditions.
