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.

该研究项目在分析和表面化学计划的支持下，重点介绍了奇异电子有机金属系统和金属烯烃复合物的协调化学研究。 韦伯教授及其学生在佛蒙特大学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。 要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设备的应用相关。 将研究金属 - 烯烃复合物，以更好地了解Ziegler-Natta催化，并寻找增强这些材料反应性的方法。 有机金属络合物的电子转移特性虽然进行了广泛的研究，但仍与这些化合物催化选择性分子转化的能力保持较差。 为了进一步理解这些反应，可以更好地利用它们为催化剂和电子设备，以进一步理解这些反应的重点。 这项工作将使用电化学和光谱法。
