Metal Oxo Complexes: Oxidation Mechanisms

有了这个奖项，无机、生物无机和有机金属化学项目支持了北卡罗来纳大学教堂山分校化学系Thomas J. Meyer博士对过渡金属配合物作为有机氧化反应催化剂的持续研究。电化学和光化学方法将用于影响和研究反应的机理。该项目的目标是设计选择性催化试剂使用氧多吡啶钌或锇配合物。新的二氧基和配体桥接体系将被合成并测试其立体特异性。还将制备氧化配合物的硝基和亚胺类似物，并对其氧化活性进行研究。将有前途的材料制成的聚合物薄膜粘附在电极上，以测试它们作为传感器的潜力。当一个氧原子直接加到醛和芳香烃上时，它们分别发生氧化生成酸和醇。这种反应在制造新的有机化合物中很重要。为了开发出能够影响这些反应的试剂，从而获得所需的产物，了解反应的细节是很重要的。在这项研究中，金属配合物提供氧原子的确切反应途径将被确定。

With this award, the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports continued research on transition metal complexes as catalysts for organic oxidation reactions by Dr. Thomas J. Meyer of the Chemistry Department, University of North Carolina at Chapel Hill. Electrochemical and photochemical methods will be used to effect and to investigate the mechanism of the reactions. The goal of the project is to design selective catalytic reagents using oxo polypyridyl complexes of ruthenium or osmium. New dioxo and ligand-bridged systems will be synthesized and tested for stereospecificity. Nitrido and imido analogues of the oxo complexes will also be prepared and investigated for oxidation activity. Thin polymeric films of promising materials will be adhered to electrodes to test their potential as sensors. Aldehydes and aromatic hydrocarbons undergo oxidation when an oxygen atom is added to them directly to form acids and alcohols, respectively. Such reactions are important in making new organic compounds. In order to develop reagents that will effect these reactions in a manner in which the products desired can be obtained, it is important to understand the details of the reactions. In this investigation, the exact pathway of reactions in which metal complexes provide an oxygen atom will be determined.
