英文摘要 | Redox-inactive metal ions are one of the most important co-factors involved in dioxygen activation and formation reactions by metalloenzymes. In this study, we have shown that the logarithm of the rate constants of electron-transfer and C−H bond activation reactions by nonheme iron(III)–peroxo complexes binding redox-inactive metal ions, [(TMC)FeIII(O2)]+-Mn+ (Mn+=Sc3+, Y3+, Lu3+, and La3+), increases linearly with the increase of the Lewis acidity of the redox-inactive metal ions (ΔE), which is determined from the gzz values of EPR spectra of O2.−-Mn+ complexes. In contrast, the logarithm of the rate constants of the [(TMC)FeIII(O2)]+-Mn+ complexes in nucleophilic reactions with aldehydes decreases linearly as the ΔE value increases. Thus, the Lewis acidity of the redox-inactive metal ions bound to the mononuclear nonheme iron(III)–peroxo complex modulates the reactivity of the [(TMC)FeIII(O2)]+-Mn+ complexes in electron-transfer, electrophilic, and nucleophilic reactions. |
