SGER: Reactivity of Carbon Monoxide with Organoaluminum and Organogallium Reagents

这笔小额资助用于无机、生物无机和有机金属化学项目的探索性研究，支持托莱多大学的马克·梅森教授研究一种不寻常的反应，即一氧化碳与铝配合并随后插入有机金属键。目的是确定一氧化碳与具有三坐标金属中心的有机铝和有机镓试剂的反应性范围。在初步实验结果的基础上，本研究试图确定一氧化碳与铝和镓的配位以及随后一氧化碳插入Al-C和Ga-C键如何被空间和电子环境以及金属调节。低配位数是由大体积的烷基、芳基、苯氧化合物、二胺和二（3-甲基lindolyl）甲烷造成的。该项目还将探索产生的酰基配合物与氢和乙烯的反应性。这项研究旨在提供更便宜的催化剂，可以将非常便宜的原料一氧化碳纳入经济上重要的有机化合物中。除了学习无机和有机金属的合成、表征和反应性外，学生们还将参观美国合成橡胶公司、BP化学、苏德化学和Zeon化学的研究和生产设施，以熟悉催化和有机铝试剂在工业中的各种应用，并向他们介绍这些领域的工作机会。

This Small Grant for Exploratory Research in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Professor Mark Mason at the Univesity of Toledo to study an unusual reaction whereby ccarbon monoxide coordinates to aluminum and subsequently inserts into an organometallic bond. The goal is to determine the scope of reactivity of carbon monoxide with organoaluminum and organogallium reagents that feature three-coordinate metal centers. Building upon preliminary experimental results, this research seeks to determine how the coordination of carbon monoxide to aluminum and gallium and its subsequent insertion of carbon monoxide into Al-C and Ga-C bonds can modulated by the steric and electronic environment and the metal. The low coordination number is imposed by bulky alkyls, aryls, phenoxides, diamides, and di(3-methylindolyl)methanes. The project will also explore the reactivity of resulting acyl complexes with hydrogen and ethylene. This research seeks to provide less expensive catalysts that can incorporate a very inexpensive feedstock, carbon monoxide, into economically important organic compounds. In addition to learning about inorganic and organometallic synthesis, characterization, and reactivity, students will tour research and production facilities at American Synthetic Rubber Corporation, BP Chemicals, Sud-Chemie, and Zeon Chemicals to familiarize them with the diverse range of applications of catalysis and organoaluminum reagents in industry, and to educate them as to the job opportunities available in these areas.
