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Ru和Os多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化学、生物无机化学和金属有机化学计划的支持。特别令人感兴趣的是可以完成四个电子转移的二氧杂配合物的反应。将合成新的化合物，其中金属氧位通过桥基连接，从而对反应进行空间控制。此外，还将对类似的亚胺类化合物的化学进行研究。将特别注意水到氧的转化，以便可以阐明氢转移步骤的性质，可能是氢化物或质子。这项基础性研究对于了解有机反应选择性催化剂的行为以及开发利用大气氧气的高效工业催化剂具有重要意义。烯烃、芳香烃、胺和其他类别的化合物可能会被开发的催化剂氧化。

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.
