Kinetic and Mechanistic Studies of Highly Reactive Species Containing Electron-Deficient Main Group Atoms, and the Synthesis of Novel Molecules

有了这个更新奖的有机和高分子化学计划继续支持彼得P加斯帕博士在化学系在圣刘易斯华盛顿大学。 这项工作的目标是了解控制缺电子和多键有机分子反应的因素，这些分子含有元素Si，P，S和Sn，以及更常见的元素如C，N和O。 人们相信，通过制造这些新分子，并研究它们的反应机理，将有可能将有机化学的强大机械论思想扩展到预测整个周期表中的成键和断裂过程。 已经开发了一种功能强大的新装置，该装置将简化新反应物种的鉴定，这可能导致具有不寻常和有用性质的新材料。待研究的一些分子是（iPr 3Si）2Si，其类似于卡宾，并且可以具有单线态或三线态电子基态，PCSiMe 3，在P和C之间具有三键，类似于有机腈，以及BN，一种不稳定的分子，已被光谱学检测到，但其化学性质尚不清楚。 BN将在新的超音速流热解喷嘴装置中产生，并在电荷交换或其他离子-分子反应后通过FT离子回旋共振质谱检测。

With this renewal award the Organic and Macromolecular Chemistry Program continues its support for the work of Dr. Peter P. Gaspar in the Department of Chemistry at Washington University in St louis. The goal of the work is to understand the factors that control the reactions of electron deficient and multiply bonded organic molecules containing the elements Si, P, S and Sn, in addition to the more common elements like C, N, and O. It is believed that by making these novel molecules, and studying the mechanisms of their reactions, it will be possible to extend the powerful mechanistic ideas of organic chemistry to the prediction of bond-making and -breaking processes throughout the periodic table. A powerful new apparatus has been developed which will simplify the identification of new reactive species which may lead to new materials with unusual and useful properties.Some of the molecules to be investigated are (iPr3Si)2Si, which is analogous to a carbene and may have either a singlet or a triplet electronic ground state, PCSiMe3, with a triple bond between the P and the C, analogous to an organic nitrile, and BN, an unstable molecule which has been detected spectroscopically but whose chemistry is unknown. BN will be generated in the new supersonic flow pyrolysis nozzle apparatus, and detected by FT ion cyclotron resonance mass spectroscopy after charge exchange or other ion-molecule reactions.
