With this award from the Chemical Synthesis (SYN) Program of the Chemistry Division, Professor T. Don Tilley and his research group in the Department of Chemistry at the University of California, Berkeley, will conduct fundamental studies of structure, bonding, and reactivity in new transition metal-main group complexes, with a particular focus on complexes with silylene ligands, LnM=SiRR'. This research is designed to provide an understanding of the mechanism and scope of a new type of hydrosilation reaction discovered in this program. This work will guide the way to more challenging catalytic hydrosilation substrates, and to other catalytic systems that utilize cost-effective, earth-abundant metals such as iron, cobalt and nickel. Efficient catalysis with first row metals is a pervasive theme attracting strong interest in the research and industrial catalysis communities, and it is therefore important to learn how such catalysts may operate.Broader impacts of this research relate to its development of new strategies for chemical conversions having potential applications in drug development, polymer and materials synthesis, and the large-scale production of value-added chemicals. The proposed basic research will contribute to the knowledge base chemists use to design new catalytic reactions that will contribute to sustainability. Furthermore, the proposed research is well suited for the training of young scientists. In addition, the PI and students involved in this project regularly participate in and lead outreach activities, such as the training of local high school students and presenting science demonstrations at a local middle school. Notably, a collaborative effort within the research group involves planning and presenting science lessons to grade school students. Group members travel to nearby elementary schools (at least two each month) and teach basic scientific principles, hoping to improve early STEM education and encourage budding scientists.

获得化学部化学合成（SYN）项目的这一奖项后，加州大学伯克利分校化学系的T. Don Tilley教授和他的研究小组将对新的过渡金属-主基团配合物的结构、键合和反应性进行基础研究，特别关注硅烯配体的配合物，LnM=SiRR'。这项研究的目的是提供的机制和范围的一个新的类型的氢化反应的理解在这个程序中发现。这项工作将指导更具挑战性的催化氢化底物，以及利用成本效益高、地球上丰富的金属（如铁、钴和镍）的其他催化系统。第一排金属的高效催化是一个普遍的主题，在研究和工业催化界引起了强烈的兴趣，因此了解这种催化剂如何运作是很重要的。这项研究的更广泛影响涉及其开发的化学转化新策略，在药物开发，聚合物和材料合成以及增值化学品的大规模生产中具有潜在的应用。提出的基础研究将有助于化学家使用知识基础来设计新的催化反应，这将有助于可持续发展。此外，拟议的研究非常适合青年科学家的培训。此外，项目负责人和参与该项目的学生定期参加并领导外联活动，如培训当地高中生，在当地一所中学进行科学演示。值得注意的是，研究小组内部的合作努力包括计划和向小学生展示科学课程。小组成员前往附近的小学（每月至少两所），教授基本的科学原理，希望改善早期的STEM教育，鼓励崭露头角的科学家。
