报告摘要
Nature has inspired inorganic chemists to look beyond the immediate coordination sphere of complexes to tune and optimize reactivity. Two important themes have been the use of pendant proton donors/acceptors as well as incorporating redox-active moieties into ligand scaffolds. However, nature does not limit itself to an “either/or” strategy, and uses both of these features in enzymatic active sites. In this talk, I will describe our laboratory’s efforts at discovering new transition metal complexes wherein the ligand scaffold can mediate both proton and electron transfer. A novel dihydrazonopyrrole ligand displays these features, and when coupled with appropriate transition metal centers enables reversible hydrogen atom transfer. Furthermore, this strategy also facilitates the oxidative activation of strong bonds. Finally, we will show how we can leverage this activity for unique dehydrogenative amination reactivity.
讲座嘉宾
John Anderson
芝加哥大学
John was born in Downers Grove, a suburb about 40 minutes west of Chicago. He acquired his interest in chemistry at an early age from his grandmother, who was a chemist at Abbott Laboratories in North Chicago. Seeking to further his study of science, John matriculated at the University of Chicago. Once there, John quickly joined the laboratory of Professor Greg Hillhouse. It was in the three years that John spent in Greg's lab that he found his love for inorganic chemistry. During this time, John focused on researching phosphine complexes of Ni, specifically with respect to their reactivity with small molecules such as carbon dioxide and carbon disulfide.
After graduating John began his graduate studies in Boston at MIT in the group of Professor Jonas Peters. His time in Boston was to be short-lived however, as the Peters group moved to the California Institute of Technology in sunny Pasadena, CA quickly thereafter. John also made the move and received his Ph.D. from Caltech. John's thesis centered around a discrete Fe complex that mediates catalytic nitrogen fixation to ammonia.
After finishing his thesis, John came to Northwestern to work in the laboratory of Dave Harris. During this time, John has focused on materials, particularly metal organic frameworks. A central theme is the ability to stabilize reactive species, such as low coordinate dioxygen adducts, within metal organic frameworks thus allowing their characterization and study.
In his independent career, John and the Anderson group have been interested in linking the physical properties of transition metal centers, particularly their spin and radical character, to reactivity and bulk properties.
朱戎
北京大学
After receiving his B.S. degree from Peking University in 2010, Rong Zhu did his Ph.D. study at MIT, where he worked on transition metal catalysis and radical chemistry in the lab of Prof. Steve Buchwald. Between 2015-2018, he performed postdoctoral research with Prof. Tim Swager on chemical sensors, responsive polymers, and anion recognition. Rong started his independent career at College of Chemistry and Molecular Engineering, Peking University in March 2018. His research interests involve catalysis and functional polymer materials.

有机化学
有机分子在人类社会中起着关键作用，它们是药物、农药、材料、燃料、保健品、食品添加剂和家用化学品的重要组成部分。我们的世界不仅需要不断地发现具备性能提升乃至于全新功能的新型有机分子，而且还需要更高效和环保的制备方法。有机化学是一门研究有机分子合成、性质和应用的基础学科，它作为核心学科为多种研究领域奠定了基础，包括但不限于药物研发，分子生物学，化学生物学，石油和环境化学，材料科学和分子工程。尽管有机化学在过去几十年间取得了长足进步，它仍然保持着快速发展。近年来，有机化学家一直致力于寻找更多高效的合成策略，以尽可能地减少合成中的废弃物和能量消耗，或用于合成具有独特功能的新颖大分子和小分子。
这次联合系列讲座的报告人来自芝加哥大学，他们将展示有机化学和金属有机化学研究领域中一些新兴的方向，例如如何在金属/无金属参与的条件下活化惰性化学键用于高效合成，如何利用氢键实现不对称催化，如何快速构建高度复杂的活性天然产物，以及如何开发有趣的“可训练”的聚合物材料。
