Synthetic Coordination Chemistry

9407284 Reed U of Southern加州南加州大学化学系的Christopher Reed博士得到了无机、生物无机和有机化学计划的支持，用于弱配位阴离子的研究。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，并且其中电荷在大体积上是离域的。这些将被用来作为抗衡离子，以获得低配位阳离子和稳定络合物的非常弱的捐助者，如氙，烃等。使用的非配位阴离子的混合中间自旋态Fe（III）配合物的磁性将被调查，以建立这些阴离子的相对配位场强度。 通常，带负电荷的化学物质（阴离子）与带正电荷的物质（阳离子）紧密结合。该项目将侧重于制备形状和电荷分布使其无法接近阳离子的阴离子。这将导致高活性阳离子，其性质将被评估。虽然有几个化学领域的影响，其中最重要的是在几个工业上重要的过程中的新催化剂的设计。

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.
