Professor Travis J. Williams of the University of Southern California is supported by the Chemical Catalysis (CAT) Program in the Division of Chemistry to develop bifunctional homogeneous catalytic systems featuring a Lewis acid that functions primarily as a directing element to impart selectivity to hydride transfer reactions and a second metal as the hydride transfer catalyst. The project includes mechanistic studies on the dehydrogenation of ammonia borane adduct and on the catalytic hydrogenation of spent ammonia borane. Plans are outlined to study C-H functionalization reactions and to develop other Ru (II) and Fe (II) borates that might exhibit interesting catalytic chemistry. If successful, the project will facilitate the chemical transformation of hydrides with bifunctional catalytic systems. The ability to manipulate hydride groups may significantly impact organic synthesis in general and hydrogen energy storage in particular. A number of courses and hands-on training of graduate and undergraduate students in NMR spectroscopy will be developed and NMR spectroscopy will be introduced to local PUIs and high schools through a cyber-enabled NMR facility.

南加州大学的Travis J. Williams教授得到了化学催化（CAT）化学分区的支持，以开发具有双功能均质催化系统，其特征是刘易斯酸的特征，该系统主要作为导演元素，主要是对氢化物转移反应的选择性，并作为氢化物转移催化剂的第二种金属转移反应。 该项目包括有关硼烷加合物的脱氢作用以及花费氨硼烷的催化氢化的机械研究。 概述了研究C-H功能化反应的计划，并开发可能表现出有趣的催化化学的其他RU（II）和Fe（II）碳酸盐。 如果成功，该项目将促进使用双功能催化系统进行氢化物的化学转化。 操纵氢化物组的能力可能会显着影响一般的有机合成，尤其是氢能储存的能力。 将开发许多NMR光谱研究生和本科生的课程和动手培训，并将通过支持网络支持的NMR设施将NMR光谱验证介绍给当地的PUI和高中。
