Design and Synthesis of Binuclear Manganese Oxidation Catalysts

在这项由无机化学、生物无机化学和金属有机化学计划支持的项目中，怀俄明大学的Derek J.Hodgson将研究中等高氧化态下锰的双核配位化合物的合成。我们将考察这些配合物的结构、氧化还原性能和电化学行为。这些化合物可用作电催化氧化剂。它们之所以令人感兴趣，也是因为它们与光系统II中的锰化合物有关，后者参与光合作用。被研究的配合物是锰(III/III)、锰(III、IV)和锰(IV、IV)与含有四个氮供体原子的辅助四齿配体的二氧二聚体。这些非卟啉配体将被各种取代基和其他结构变化修饰，从而使配合物的氧化还原行为以可预测的方式变化。

In this project supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, Derek J. Hodgson of the University of Wyoming will investigate the synthesis of binuclear coordination compounds of manganese in moderately high oxidation states. The structures, oxidation-reduction properties and the electrochemical behavior of these complexes will be examined. The compounds may be useful as electrocatalytic oxidants. They are also of interest bcause they are related to the manganese compounds of Photosystem II, which is involved in photosynthesis. The complexes to be investigated are mu-dioxo dimers of manganese(III/III), manganese(III,IV) and manganese(IV,IV) with auxiliary tetradentate ligands containing four nitrogen donor atoms. These non-porphyrinic ligands will be modified with various substituents and other structural changes so as to cause the redox behavior of the complexes to vary in a predictable manner.
