Radical Cage Effects in Organometallic Chemistry and Reactions of Molybdocenes in Aqueous Solution

俄勒冈州大学（尤金）化学系的大卫泰勒博士得到了化学系无机、生物无机和有机化学项目的支持，研究（i）自由基物质的化学和（ii）水介质中异癸烯的化学。在第一部分中，PI将研究机制和合成中的自由基途径，这是有机金属化学中的主导主题。具体来说，他将研究笼效应在自由基化学和探索溶剂笼的作用，以实现自由基系统的更全面的理解。他将采用飞秒激光泵浦探测技术来探测短寿命的自由基笼对，并评估笼的反应性。在第二部分，PI将研究水溶液中的降冰片烯的反应性，以研究乙烯基聚合反应，腈水解，氢化反应，乙二醇合成和Reppe化学的催化作用。参与项目的学生将获得各种技能的良好培训，如合成，激光光谱和动力学，光化学，他们将有能力为研究和教育作出重大贡献。第一部分的研究结果将有助于提高我们对自由基反应的整体认识;第二部分的研究结果将对绿色化学的未来发展产生重大影响。

Dr. David Tyler of the Department of Chemistry, University of Oregon (Eugene), is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program of the Division of Chemistry to investigate (i) the chemistry of radical species and (ii) the chemistry of molybdenocenes in aqueous media. In the first part the PI will examine radical pathways in mechanisms and in syntheses, that are a dominant theme in organometallic chemistry. Specifically, he will investigate cage effects in radical chemistry and explore the role of the solvent cage so as to achieve a fuller understanding of radical systems. He will employ femtosecond laser pump-probe techniques to probe the short-lived radical cage pairs and to assess cage reactivity. In the second part, the PI will investigate the reactivity of molybdenocenes in aqueous solutions to study the catalysis of vinyl polymerization reactions, nitrile hydrolyses, hydrogenation reactions, ethylene glycol synthesis, and Reppe chemistry.Students working on the projects will gain excellent training in a diverse set of skills such as syntheses, laser spectroscopy and dynamics, photochemistry, among others.They will be well equipped to make significant contributions to research and education. The results of the first part of the project will help improve our overall understanding of radical reactions; results from the second part will have a great impact on future developments of green chemistry.
