9412964詹克斯爱荷华州立大学将研究芳香族亚硫醚的光化学和光物理。我们将致力于三个具体的目标：(1)阐明芳香族亚砜的光物理，包括激发态的性质和分子间猝灭的机理；(2)详细研究下列光化学反应和主要的机理步骤：硫的立体化学转化、a-裂解、氢原子提取、脱氧和烯烃加成；(3)基于对反应机理的理解设计几类有用的转化。实验研究将与分子轨道计算相结合。来自有机动力学项目的这笔赠款支持爱荷华州立大学威廉·S·詹克斯教授的工作。将研究一类有机化合物的光化学和光物理。这些化合物的特征是硫键与一个氧原子和苯基团相连。后者有时被称为芳香族，由环上键合的六个碳原子组成。我们将详细研究这些化合物在紫外光照射下发生反应的各个步骤。这些研究将为设计有用的合成复杂有机分子的路线奠定基础。

9412964 Jenks Iowa State University The photochemistry and photophysics of aromatic sulfoxides will be studied. Three specific objectives will be pursued: (1) Elucidation of the photophysics of aromatic sulfoxides, including the nature of the excited states and mechanisms of intermolecular quenching, (2) A detailed study of the following photochemical reactions and primary mechanistic steps: stereochemical inversion at sulfur, a-cleavage, hydrogen atom abstraction, deoxygenation, and addition to olefins, (3) The design of classes of useful transformations based on mechanistic understanding of the reaction. The experimental studies will be coupled with molecular orbital calculations. This grant from the Organic Dynamics Program supports the work of Professor William S. Jenks at Iowa State University. Photochemistry and Photophysics of a class of organic compounds will be studied. These compounds are characterized by having sulfur bonded to one oxygen atom and to a benzene-type group. The latter group is sometimes referred to as aromatic, and consists of six-carbon atoms bonded in a ring. The individual steps by which these compounds undergo reaction upon radiation with ultraviolet light will be investigated in detail. These studies will form the basis for the design of useful synthetic routes to complex organic molecules.
