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.

在这个由化学部化学催化项目资助的项目中，加州大学伯克利分校化学系T. Don Tilley教授及其研究小组对新型过渡金属的结构、键合和反应性进行了基础研究-主要群复合体。在该项目中，正在开发化学转化的新策略。这些技术可应用于药物开发、聚合物和材料合成以及增值化学品的大规模生产。 年轻科学家正在接受催化剂开发领域的培训。此外，蒂莉教授和参与该项目的学生还参与并领导了外展活动，例如培训当地高中生以及在当地中学进行科学演示。值得注意的是，研究小组内部的合作包括为小学生规划和教授科学课程。小组成员前往附近的小学（每月至少两次）教授基本科学原理，希望改善早期 STEM 教育并鼓励崭露头角的科学家。该项目重点研究具有亚硅基配体的配合物，LnM=SiRR'。这项研究旨在提供对本项目中发现的新型硅氢化反应的机制和范围的理解，并为更具挑战性的催化硅氢化反应提供指导。此外，该项目还研究利用具有成本效益、地球储量丰富的金属（如铁、钴和镍）的催化系统。第一排金属的高效催化是一个普遍的主题，引起了研究和工业催化界的浓厚兴趣，因此了解此类催化剂的运作方式非常重要。
