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.

本研究项目由分析和表面化学计划支持，重点研究奇数电子有机金属体系和金属-烯烃络合物的配位化学。 在这项工作中，佛蒙特大学的韦伯教授和他的学生将使用各种电化学和光谱电化学方法以及电子顺磁共振光谱。 待研究的有机金属体系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。 金属-烯烃络合物将被研究以更好地理解齐格勒-纳塔催化并寻找提高这些材料的反应性的方法。 有机金属配合物的电子转移性质，而广泛的研究，仍然很少与这些化合物的能力，催化选择性的分子转化。 奇电子金属配合物将是本工作的重点，以进一步了解这些反应，使其能够更好地开发作为催化剂和电子器件。 电化学和光谱学方法将用于这项工作。
