NEUTRAL PRODUCTS FROM IONIC REACTIONS IN THE GAS PHASE

加州大学河滨分校。他使用了三种实验技术来研究气相中的有机反应：从专门设计的产生气体离子的电子轰击流动反应堆收集中性反应产物，碳键氚的变形产生碳离子和3He，以及质谱学。五种类型的实验说明了化学的范围：欧米伽-烯基阳离子的环化，羟化碳阳离子的重排，三甲基硅基阳离子促进的气态羰基化合物的还原，通过T+在醚氧上的沉积产生烷基阳离子，以及从高压气体到超临界流体的中性氚产物的变化。莫顿博士的工作使用了一种独特的电子轰击流动反应堆，在该反应堆中，电子束沿着封闭在螺线管电磁铁中的低压反应容器的中心向下传递。有了它，他能够捕获和分析气相反应的中性(未带电)分子产物，以及电子碰撞产生的带电粒子。带电粒子也可以通过氚分子的β衰变而产生。通过这些方法，莫顿博士能够研究一些重要类型的有机反应的细节，并开发新的仪器方法来分析标记反应物中的中性化合物的结构及其同位素分布。

University of California at Riverside. He uses three experimental techniques to study organic reactions in the gas phase: collection of the neutral reaction products from a specially designed Electron Bombardment Flow reactor which produces gaseous ions, transmutation of C-bonded tritium to give carbonium ions and 3He, and mass spectroscopy. Five types of experiments illustrate the scope of the chemistry: cyclization of omega-alkenyl cations, rearrangements of hydroxylated carbocations, reduction of gaseous carbonyl compounds promoted by trimethylsilyl cations, production of alkyl cations via the deposition of T+ onto ether oxygens, and changes in the neutral tritiated products on going from a high pressure gas to a supercritical fluid. Dr. Morton's work uses a unique Electron Bombardment Flow reactor in which an electron beam is passed down the center of a low pressure reaction vessel enclosed in a solenoid electromagnet. With it, he is able to trap and analyze the neutral (uncharged) molecular products of gas phase reactions, as well as the charged particles produced by electron collisions. Charged particles can also be produced by beta-decay of tritiated molecules. With these methods, Dr. Morton is able to study the details of some important types of organic reactions, and to develop new instrumental approaches for analyzing the structures of neutrals from labeled reactants and their isotopic distributions.
