The focus of this research is the use of the Murai reaction to achieve the efficient RU catalyzed addition of ortho aromatic C-H bonds of acetophenone across the C-C double bonds of alpha, omega dienes.. The scope and mechanism of this regioselective reaction will be probed. The photoreactivity of polymer bound o-alkyl aromatic groups will be studied and materials with unusual uv stability will be sought. Hyperbranched materials and polymers containing nonlinear optical chromophores will also be prepared. With this new award, the Organic Dynamics Program is supporting the research of Dr. William P. Weber of the Department of Chemistry at the University of Southern California. Professor Weber will focus his work using Ruthenium catalyzed polymerization to produce a series of novel polymers. It is possible that these materials will have unusual stability towards uv photodegradation. Novel hyperbranched materials and materials containing nonlinear optical (NLO) chromophores will also be prepared.

本研究的重点是利用Murai反应实现Ru催化的苯乙酮邻位芳香族C-H键跨越α，omega-dienes的C-C双键的高效加成反应。对该区域选择性反应的范围和机理进行了探讨。将研究聚合物结合邻烷基芳香族基团的光反应性，并寻找具有特殊紫外线稳定性的材料。还将制备含有非线性光学发色团的超支化材料和聚合物。有了这个新的奖项，有机动力学项目将支持南加州大学化学系的威廉·P·韦伯博士的研究。韦伯教授将专注于他的工作，使用Ru催化聚合来生产一系列新型聚合物。这些材料有可能对紫外光降解具有不寻常的稳定性。还将制备新型超支化材料和含有非线性光学(NLO)生色团的材料。
