研究了一系列二茂铁衍生物在脱氧乙腈中还原非血红素氧铁（IV）配合物的电子转移动力学，并根据马库斯电子转移理论对结果进行了评估，以确定电子转移的重组能和非血红素氧铁（IV）配合物的单电子还原电位。与血红素氧铁（IV）配合物相比，非血红素氧铁（IV）配合物具有更大的电子转移重组能和更低的单电子还原电位。
Electron-transfer kinetics for the reduction of non-heme oxoiron(IV) complexes by a series of ferrocene derivatives were examined in deaerated acetonitrile, and the resulting data were evaluated in light of the Marcus theory of electron transfer to determine the reorganization energies of electron transfer and the one-electron reduction potentials of non-heme oxoiron(IV) complexes. The electron-transfer properties of non-heme oxoiron(IV) complexes are featured by the larger reorganization energies of electron transfer and the lower one-electron reduction potentials as compared with those of heme oxoiron(IV) complexes.
