With funding from the Organic Dynamics Program, Professor Steven R. Kass of the University of Minnesota-Twin Cities will study organic ion-molecule reactons in the gas phase. A unique variable temperature flowing afterglow-triple quadrupole aparatus forms the experimental basis for the work. In some cases, solution studies will be performed on the same species. Results will be supplemented with ab initio molecular orbital calculations. Particular attention will be given to antiaromatic ions, unimolecular rearrangements, and the effect of (particularly remote) substituent effects on ion reactivity and stability. These experiments will provide fundamental understanding of certain elusive and highly unstable reactive intermediates, including a class for which no previous experimental information has been available. Experiments such as those which will be performed provide the hard-core data on which the rules of organic chemistry are built, and extrapolation of the basic results obtained in the gas phase to solution, where most preparative organic chemistry is done, will have substantial impact on theory and potentially on practice in organic chemistry. f8 Û-ª þ + Ûª▓ ÑOh ª' +'ª▒0 Ý + ] $ H l + ¢ ╗ D h + ++++++++++++++++++++++++++++++++ R:\WWUSER\TEMPLATE\NORMAL.DOT

在有机动力学项目的资助下，史蒂文·R·明尼苏达大学双城分校的卡斯将研究气相中的有机离子分子反应。 一个独特的变温流动余辉-三重四极杆装置构成的工作的实验基础。 在某些情况下，将对相同种属进行溶液研究。 结果将补充从头计算分子轨道计算。 特别注意将给予反芳族离子，单分子重排，和离子的反应性和稳定性（特别是远程）取代基的影响。 这些实验将提供某些难以捉摸的和高度不稳定的反应中间体，包括一个类，其中没有以前的实验信息已经提供了基本的理解。 实验，如那些将被执行提供的有机化学的规则是建立在核心数据，并在气相中获得的基本结果外推到解决方案，其中大多数制备有机化学做，将有重大影响的理论和潜在的有机化学实践。 f8-？ + 你好，我的天啊 Ý + ] $ H L + ¢ ╗ D H + ++++++++++++++++++++++++++++++++ R:\WWUSER\TEMPLATE\NORMAL.DOT
