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教授在化学系化学催化(CAT)计划的支持下，开发了双功能均相催化系统，其特点是主要用作引导氢化物转移反应的直接元素，以及第二种金属作为氢化物转移催化剂。该项目包括对氨基硼烷加合物脱氢和废氨基硼烷催化加氢的机理研究。概述了研究C-H官能化反应和开发其他可能显示出有趣的催化化学的Ru(II)和Fe(II)硼酸盐的计划。如果成功，该项目将利用双功能催化系统促进氢化物的化学转化。操纵氢化物基团的能力可能会对有机合成特别是氢能储存产生重大影响。将开发一系列课程和对研究生和本科生的核磁共振波谱实践培训，并将通过网络使能的核磁共振设施将核磁共振波谱介绍给当地的PUI和高中。
