Inorganic Redox Mechanisms in Solution

肯特州立大学化学系的埃德温·S·古尔德博士在无机化学、生物无机化学和金属有机化学项目中得到支持，主要研究强调不常见氧化态的溶液相氧化还原反应。将研究三个领域：1)2电子氧化剂的折衷氧化还原行为，其中2E-还原剂通过单电子路径反应；2)超氧化物-金属相互作用，强调金属催化与非金属反应物的反应；3)与光系统II有关的多核锰配合物，处理被认为参与光合作用将水转化为氧的高价锰状态。在纯化学和应用化学的几乎所有领域中，电子在反应物之间转移的反应都是非常重要的。古尔德研究的一部分阐述了在某些情况下，当两个电子通过两个独立但密切相关的路径离开还原剂时，转移是如何发生的。在第二部分，他研究了超氧化物-金属络合物和非金属反应物之间的电子转移。这与超氧化物的解毒有关，这是一个重要的生化过程。第三，他正在确定锰离子在光合作用反应中的作用，这与植物在光合作用过程中产生氧气的方式有关。

Dr. Edwin S. Gould, Chemistry Department, Kent State University, is supported in the Inorganic, Bioinorganic, and Organometallic Chemistry Program, for investigations of solution phase oxidation-reduction reactions which emphasize less common oxidation states. Three areas will be studied: 1) compromised redox behavior of 2-electron oxidants in which 2e-reductants react through single electron paths; 2) superoxide-metal interactions, emphasizing metal catalyzed reactions with nonmetal reactants; and 3) polynuclear manganese complexes related to Photosystem II, dealing with hypervalent manganese states which are thought to be involved in the photosynthetic conversion of water to oxygen. Reactions in which electrons are transferred between reactants are of enormous importance in virtually all areas of pure and applied chemistry. One portion of Gould's research addresses how transfer occurs in some cases when two electrons leave a reductant through two separate, but closely related, pathways. In a second part, he studies the electron transfer between superoxide-metal complexes and non-metal reactants. This is related to the detoxification of superoxide, which is an important biochemical process. Third, he is determining the role of manganese ions in photosynthetic reactions, which is related to the way plants generate oxygen during photosynthesis.
