Chemistry of Metal Oxo Complexes and Oxidation Mechanisms

北卡罗来纳大学教堂山分校化学系的Thomas J. Meyer博士将继续研究高氧化态钌和锇聚吡啶配合物氧化有机底物的详细机制。这项工作将得到无机、生物无机和有机金属化学计划的支持。特别令人感兴趣的是能完成4个电子转移的二氧配合物的反应。新的化合物将被合成，其中的金属-氧位点通过桥接基团连接，从而对反应进行空间控制。此外，还将研究类似的亚胺配合物的化学性质。将特别注意水到氧的转换，以便氢转移步骤的性质，可能作为氢化物或质子，可以阐明。这项基础研究对于理解有机反应中选择性催化剂的行为以及开发利用大气氧的有效工业催化剂具有重要意义。烯烃、芳烃、胺和其他种类的化合物可被所开发的催化剂氧化。

Dr. Thomas J. Meyer of the Chemistry Department, University of North Carolina at Chapel Hill, will continue to study the detailed mechanisms for oxidation of organic substrates by high oxidation state ruthenium and osmium polypyridyl complexes. This work will be supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program. Of particular interest are reactions of di-oxo complexes which can accomplish the transfer of four electrons. New compounds will be synthesized in which the metal-oxo sites are linked by briding groups, thus giving spatial control to the reaction. In addition, the chemistry of the analogous imido complexes will be investigated. Special attention will be paid to aqua to oxo conversions, so that the nature of the hydrogen transfer step, perhaps as hydride or a proton, can be elucidated. %%% This fundamental research is relevant to understanding the behavior of selective catalysts for organic reactions and the development of effective industrial catalysts which utilize atmospheric oxygen. Olefins, aromatic hydrocarbons, amines, and other classes of compounds might be oxidized by the catalysts developed.
