项目摘要
In this project supported by the Chemical Structure, Dynamics and Mechanisms Program of the Division of Chemistry, Professor William Taylor of the University of Central Arkansas and his undergraduate research team will examine the activation of sigma bonds in halogenated molecules by metal ions. The reactions of interest will be carried out in the gas phase using a selected ion drift cell reactor which will generate transition metal ions in both ground and excited electronic states using a sputtering glow discharge source. These ions will then be mass selected via a quadrupole mass filter and introduced into a drift cell containing low pressures of helium and the neutral reactant molecule of interest. Subsequent analysis of reaction products will be carried out using a second quadrupole. This instrument will also be used to characterize the metal ion electronic state distributions via electronic state chromatography (ESC). ESC will also be used to determine the state-specificity of reaction products. Neutral reaction species will include various halogenated methanes (CH3X, CF3X, where X =Cl, Br and I), SF5Cl and SF5Br, and others. The experiments are designed to reveal the dependence of reaction outcome (e.g., halogen or halide abstraction, HX elimination) on various parameters, including the electronic state of the metal species as well as structural characteristics of the reactant neutral. Temperature dependent kinetic studies of selected reactions will be aimed at identifying likely transition states. These experimental efforts will be complemented by ensity functional calculations of reaction potential energy surfaces. Transition metal ions have the ability to break sigma bonds, and this property is most useful in converting hydrocarbons to other, more useful compounds. Understanding the mechanism of this process will allow design of new and better catalysts for use in chemical synthesis and the petroleum industry. In addition, the project will provide research opportunities to undergraduates in an area which they might not otherwise be exposed to. Undergraduates participating in this work benefit from a valuable research experience which serves them well in a variety of subsequent career choices including graduate/professional programs and science-related jobs.
在这个由化学系化学结构、动力学和机制项目支持的项目中,中阿肯色大学的威廉·泰勒教授和他的本科研究小组将研究金属离子对卤化分子中sigma键的激活。感兴趣的反应将在气相中进行,使用选定的离子漂移电池反应器,该反应器将使用溅射辉光放电源产生基态和激发态的过渡金属离子。然后,这些离子将通过四极质量过滤器进行质量选择,并引入含有低压氦和感兴趣的中性反应物分子的漂移池。反应产物的后续分析将使用第二个四极杆进行。该仪器还将通过电子态色谱(ESC)表征金属离子的电子态分布。ESC也将用于确定反应产物的状态特异性。中性反应物质包括各种卤化甲烷(CH3X, CF3X,其中X =Cl, Br和I), SF5Cl和SF5Br等。实验旨在揭示反应结果(例如卤素或卤化物的提取,HX的消除)对各种参数的依赖,包括金属物种的电子状态以及反应物中性的结构特征。选定反应的温度依赖动力学研究将旨在确定可能的过渡态。这些实验成果将由反应势能面密度泛函计算加以补充。过渡金属离子具有破坏sigma键的能力,这种性质在将碳氢化合物转化为其他更有用的化合物时非常有用。了解这一过程的机理将有助于设计出新的、更好的催化剂,用于化学合成和石油工业。此外,该项目将为本科生提供他们可能不会接触到的领域的研究机会。参与这项工作的本科生受益于宝贵的研究经验,这对他们随后的各种职业选择有很好的帮助,包括研究生/专业课程和科学相关的工作。
