Studies on the Photophysics and Photochemistry of Aromatic Sulfoxides

[9412964] Jenks Iowa州立大学将研究芳香亚砜的光化学和光物理。本研究将有三个具体目标：(1)阐明芳香亚砜的光物理性质，包括激发态的性质和分子间猝灭的机制；(2)详细研究以下光化学反应和主要机理步骤：(3)基于对反应机理的理解，设计各类有用的转化。实验研究将与分子轨道计算相结合。这项来自有机动力学项目的资助支持了爱荷华州立大学威廉·s·詹克斯教授的工作。本课程将学习一类有机化合物的光化学和光物理。这些化合物的特点是硫与一个氧原子和一个苯型基团相连。后一组有时被称为芳香族，由六个碳原子键成一个环。这些化合物在紫外线照射下发生反应的各个步骤将被详细研究。这些研究将为设计合成复杂有机分子的有效途径奠定基础。

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.
