Design and Synthesis of Binuclear Manganese Oxidation Catalysts

在该项目中，无机、生物无机和 有机化学计划，德里克J霍奇森的 怀俄明州大学将研究合成 双核锰配合物 高氧化态。结构、氧化还原 这些配合物的性质和电化学行为 将被审查。所述化合物可用作 电催化氧化剂它们也很有趣， 它们与光系统II的锰化合物有关， 参与光合作用。 待研究的络合物是以下的μ-二氧代二聚体： 锰（III/III）、锰（III，IV）和锰（IV，IV）与 含四个氮给体的辅助四齿配体 原子的这些非卟啉配体将被修饰， 各种取代基和其他结构变化， 导致复合物的氧化还原行为以 可预测的方式。

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.
