Abstract
The redox properties of the μ-η2:η2 peroxo complex [Cu2(H6M4h)(O2)]2+ were elucidated. This study constitutes the first full electrochemical and spectroelectrochemical characterization of a side-on peroxo Cu2:O2 bioinorganic model complex. The peroxo complex is irreversibly reduced in a two-electron process localized on the peroxo ligand triggering the cleavage of the O-O bond.
摘要
阐明了 μ-η2:η2 过氧配合物 [Cu2(H6M4h)(O2)]2+ 的氧化还原性质。这项研究构成了首例对侧过氧 Cu2:O2 生物无机模型配合物的全电化学和光谱电化学特征研究。过氧配合物不可逆地在两个电子过程中被还原，该过程定位在过氧配体上，引发 O-O 键的断裂。
