项目摘要
With the support of the Organic Dynamics Program in the Chemistry Division, Professor Paul Wenthold, of the Department of Chemistry at Purdue University, will investigate pericyclic reactions of ions using flowing afterglow/photoelectron spectroscopy. Among the reactions examined are radical cationic and radical anionic Cope and Diels-Alder reactions. The goal of the work will be to determine the products of the reaction, the mechanism by which they are formed, and the catalytic role of ionization. Solvated ions will be used to probe the role of solvent in determining reaction products. The proposal outlines an extensive program of experimentation to characterize the structure and reactivities of various ion radicals and related novel species, using the specialized capabilities of advanced flowing afterglow instrumentation and a negative ion photoelectron spectrometer now under construction at Purdue. While theory-based calculations will play a role, the main emphasis is clearly on defining structures and patterns of reactivity experimentally. The proposal rests on the curiosity of a mechanistically concerned physical organic chemist fully equipped with the more specialized technical repertoire of an experienced gas-phase ion chemist. Much new information and non-trivial conceptual advances should be gained. Professor Paul Wenthold, of the Department of Chemistry at the Purdue University, with the support of the Organic Dynamics Program, will also continue to train students who will become an integral part of the research and publications resulting from the work. The research results will provide a fresh understanding of novel structures and chemical transformations while demonstrating new applications of emerging technical/instrumental capabilities.
在化学系有机动力学项目的支持下,普渡大学化学系的Paul Wenthold教授将使用流动余辉/光电子能谱研究离子的周环反应。所研究的反应包括自由基阳离子和自由基阴离子科普和狄尔斯-阿尔德反应。这项工作的目标是确定反应的产物,它们形成的机制以及电离的催化作用。溶剂化离子将用于探测溶剂在测定反应产物中的作用。该提案概述了一个广泛的实验方案,以表征各种离子自由基和相关新物种的结构和反应性,使用先进的流动余辉仪器和负离子光电子能谱仪的专业能力,目前正在普渡大学建设。 虽然基于理论的计算将发挥作用,但主要重点显然是实验上定义反应性的结构和模式。 该建议依赖于好奇心的机械有关的物理有机化学家完全配备了更专业的技术剧目的经验丰富的气相离子化学家。 应该获得许多新的信息和重要的概念进展。普渡大学化学系的Paul Wenthold教授在有机动力学项目的支持下,也将继续培训学生,他们将成为这项工作所产生的研究和出版物的一个组成部分。研究结果将提供对新结构和化学转化的新理解,同时展示新兴技术/仪器能力的新应用。
