Electron - Transfer Induced Changes in Ligand Hapticity and Reactivity

本研究项目由分析与表面化学计划资助，主要研究奇电子有机金属体系和金属-烯烃配合物的配位化学。韦伯教授和他在佛蒙特大学的学生将在这项工作中使用各种电化学和光谱电化学方法以及电子顺磁共振波谱学。所研究的有机金属系统包括环戊二烯基和三（吡唑基）硼酸盐配体配合物，这些化合物与涉及电子器件的应用有关。研究金属-烯烃配合物，以更好地理解齐格勒-纳塔催化作用，并寻找提高这些材料反应活性的方法。有机金属配合物的电子转移性质虽然被广泛研究，但与这些化合物催化选择性分子转化的能力相关性仍然很差。为了进一步了解这些反应，奇电子金属配合物将成为这项工作的重点，以便更好地利用它们作为催化剂和电子器件。电化学和光谱方法将用于这项工作。

This research project, supported by the Analytical and Surface Chemistry Program, focuses on the study of the coordination chemistry of odd-electron organometallic systems and metal-olefin complexes. Professor Weber and his students at the University Vermont will use a variety of electrochemical and spectroelectrochemical methods together with electron paramagnetic resonance spectroscopy in this work. The organometallic systems to be studied include cyclopentdienyl and tris-(pyrazolyl)borate ligand complexes and these compounds have relevance to applications involving electronic devices. Metal-olefin complexes will be studied to better understand Ziegler-Natta catalysis and to search for ways to enhance the reactivities of these materials. The electron transfer properties of organometallic complexes, while extensively studied, remain poorly correlated with the ability of these compounds to catalyze selective molecular transformations. Odd-electron metal complexes will be the focus of this work in order to further understanding of these reactions so that they can be better exploited as catalysts and electronic devices. Electrochemical and spectroscopic methods will be used in this work.
