In this project funded by the Chemical Catalysis Program of the Chemistry Division, Professor T. Don Tilley and his research group in the Department of Chemistry at the University of California, Berkeley, conducts fundamental studies of structure, bonding, and reactivity in new transition metal-main group complexes. In this project, new strategies for chemical conversions are being developed. These have applications in drug development, polymer and materials synthesis, and the large-scale production of value-added chemicals. Young scientists are being trained in the area of catalyst development. In addition, Professor Tilly and the students involved in this project 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.This project focuses 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 and guides the way to more challenging catalytic hydrosilations. In addition, this program investigates 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.

在本研究项目中，T。加州大学伯克利分校化学系的Don蒂利和他的研究小组对新型过渡金属-主族络合物的结构、成键和反应性进行了基础研究。在该项目中，正在制定新的化学转化战略。这些应用于药物开发，聚合物和材料合成以及增值化学品的大规模生产。 正在对年轻科学家进行催化剂开发方面的培训。此外，蒂利教授和参与该项目的学生还参与并领导外联活动，如培训当地高中生和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涉及规划和向小学生提供科学课程。小组成员前往附近的小学（每月至少两次），教授基本的科学原理，希望改善早期STEM教育，鼓励崭露头角的科学家。该项目重点是与亚甲硅烷基配体的复合物，LnM= SiRR '。这项研究旨在了解该计划中发现的新型硅氢化反应的机理和范围，并为更具挑战性的催化硅氢化反应提供指导。此外，该计划还研究了利用具有成本效益的，地球上丰富的金属，如铁，钴和镍的催化系统。第一行金属的高效催化是一个普遍的主题，吸引了研究和工业催化界的强烈兴趣，因此重要的是要了解这些催化剂如何运作。
