Gas Phase and Related Studies of Organosilicon Compounds

来自有机动力学项目的这笔拨款支持了丹佛科罗拉多大学罗伯特·达姆劳尔博士的持续工作，他正在研究有机硅的反应。碳化合物和硅化合物的比较研究将使我们对硅化合物的化学性质有一个更好的基本理解，从而使硅化合物在有机合成中得到广泛的应用。Damrauer博士进行的实验将集中在两个方面。首先，硅笼化合物和硅环丁烷的缩合相研究将探索硅在极端分子环境中的反应性。其次，气相离子分子化学将用于硅阴离子及其相应的中性物质的制备和研究。后一项研究将使用串联流动余辉技术进行，它们将提供有关有机硅化合物的热化学、反应性和取代基效应的直接信息。

This grant from the Organic Dynamics Program supports the continuing work of Dr. Robert Damrauer at the University of Colorado at Denver, who is investigating the reactions of organosilicon species. This comparative study of carbon and silicon compounds will afford a better fundamental understanding of the chemical properties that allow silicon compounds to be widely used in organic synthesis. The experiments to be carried out by Dr. Damrauer will focus on two areas. First, condensed-phase studies of silicon cage compounds and silacyclobutanes will probe the reactivity of silicon placed in extreme molecular environments. Second, gas-phase ion-molecule chemistry will be used to prepare and study silicon anions along with their corresponding neutral species. The latter studies will be carried out using tandem flowing-afterglow techniques, and they will afford direct information about thermochemistry, reactivities, and substituent effects in organosilicon compounds.
