Sterically and Electronically Modified Terphenyl Ligands in Main Group Chemistry

无机化学、生物无机化学和金属有机化学项目的这一奖项支持加州大学戴维斯分校的菲利普·鲍尔教授的研究，目的是合成和表征由修饰的三联苯配体保护和稳定的新的主族化合物。这项研究考察了一些化合物中元素-元素键的基本特征，如硼烯(单价、单体有机硼化合物(I)化合物)、具有假定的双键的二硼烯和双烯，以及具有硅-硅三键的二硅炔。新化合物的结构、成键和化学将通过多核和动态核磁共振、UV-Vis、IR、EPR和X-射线结晶学进行研究，以便将传统的价态、轨道重叠、杂化和键序难以描述的成键和电子变化联系起来。这一研究将促进对主要族元素包括硅、硼、铝和镓的成键的基本理解。研究生、本科生和博士后助理将在前沿的合成无机化学项目中获得出色的培训和研究经验。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Philip Power of the University of California at Davis to synthesize and characterize new main group compounds that are protected and stabilized by modified terphenyl ligands. This research investigates the fundamental characteristics of element-element bonding in compounds such as borylenes (univalent, monomeric organoboron(I) compounds), diborenes and dialuminenes with putative double bonds, and disilynes with silicon-silicon triple bonds. The structures, bonding and chemistry of the new compounds will be examined by multinuclear and dynamic NMR UV-Vis, IR, EPR and X-ray crystallography in order to correlate bonding and electronic changes that are difficult to describe in traditional terms of valency, orbital overlap, hybridization and bond order.This research will advance the fundamental understanding of the bonding of the main group elements including silicon, boron, aluminum and gallium. Graduate students, undergraduate students and postdoctoral associates will receive excellent training and research experiences in a forefront synthetic inorganic chemistry program.
