Synthetic Coordination Chemistry

9407284南加州大学Reed U克里斯托弗·里德博士，南加州大学化学系，由无机化学、生物无机化学和有机金属化学项目支持，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，这些阴离子不包含良好的配位位置，并且电荷在大体积上被离域。这些离子将被用作反离子，以获得低配位阳离子和稳定非常弱施主的络合物，如氙气、碳氢化合物等。利用非配位阴离子的性质，研究掺杂的中间自旋态Fe(III)络合物的磁性，以确定这些阴离子的相对配位场强度。一般来说，带负电荷的化学物种(阴离子)与带正电荷的物种(阳离子)紧密结合。这个项目将专注于阴离子的制备，其形状和电荷分布使其不能接近阳离子。这将导致高活性阳离子，其性质将被评估。虽然这涉及到几个化学领域，但最重要的是为几个工业上重要的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.
