Synthetic Coordination Chemistry

Christopher Reed博士，南加州大学化学系，受到无机、生物无机和有机金属化学项目的支持，研究弱配位阴离子。在这项研究中，Reed将制备各种新的阴离子，这些阴离子不含良好的配位位点，并且在很大的体积上电荷是离域的。这些离子用作反离子，既可以获得低配位阳离子，也可以稳定氙、碳氢化合物等弱供体的配合物。利用非配位阴离子研究混合-中间自旋态Fe（III）配合物的磁性，以确定这些阴离子的相对配体场强。一般来说，带负电荷的化学物质（阴离子）与带正电荷的化学物质（阳离子）紧密结合。这个项目将专注于阴离子的制备，其形状和电荷分布阻止它们接近阳离子。这将产生高活性的阳离子，其性质将被评估。虽然这对化学的几个领域有影响，但其中最重要的是为几个重要的工业过程设计新的催化剂。

9407284 Reed U of Southern California Dr. Christopher Reed, Chemistry Department, University of Southern California, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program for the study of weakly coordinating anions. In this study, Reed will prepare a variety of new anions which contain no good coordination sites and in which the charge is delocalized over a large volume. These will be used as counter ions both to obtain low-coordinate cations and to stabilize complexes of very weak donors such as xenon, hydrocarbons, etc. Using the of non-coordinating anions the magnetic properties of admixed-intermediate spin state Fe(III) complexes will be investigated order to establish the relative ligand field strengths of these anions. In general, negatively charged chemical species (anions) tightly associate with species bearing a positive charge (cations). This project will focus on the preparation of anions whose shape and charge distribution prevents them from closely approaching a cation. This will result in highly reactive cations, whose properties will be evaluated. While there are implications to several areas of chemistry, one of the most important is in the design of new catalysts for several industrially important processes.
