The Chemistry of Unsaturated Transition Metal-Silicon Compounds

教授唐蒂利，化学系，加州大学伯克利分校是由无机，生物无机和有机化学计划的支持，以制备和研究硅基化合物和材料，具有化学，结构和电子性能，使他们潜在的适合于各种科学和技术应用。所采用的主要策略是使用过渡金属试剂和催化剂，这些试剂和催化剂（多年来）已导致大量重要的碳基产品的生产。在本实例中，努力将集中于通过首先检查硅物质（例如，亚甲硅烷基，SiR 2;硅烯，R2 Si = SiR '2等）的基本转化来制造“类似”但基于硅的材料。特别是LnM= SiR 2系统）在金属中心，并随后通过探索这些物种的结构，键合，和结构反应性关系。蒂利教授一直是金属硅化合物合成方法开发的领导者。还将努力瞄准含有不饱和硅和锗原子的新π系统，希望这些新系统将提供一些不寻常的电子特性，这些特性可能会让位于在硅和锗中包含双键的共轭大分子。

Professor Don Tilley, Department of Chemistry, University of California at Berkeley is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to prepare and investigate silicon-based compounds and materials that possess chemical, structural and electronic properties making them potentially suitable for diverse scientific and technological applications. The principal strategy employed is to use transition metal reagents and catalysts that has resulted (through the years) in the production of a wealth of important carbon-based products. In the present instance, efforts will be focussed towards making "analogous" but silicon-based materials by examining first the fundamental transformations of silicon species (e.g. silylene, SiR2; silenes, R2Si=SiR'2, etc..particularly LnM=SiR2 systems) at the metal centers, and subsequently by exploring the structures, bonding, and structure-reactivity relationships in these species. Professor Tilley has been a leader in developing synthetic methodologies in metal-silicon compounds. Efforts will also be expended towards targeting new pi-systems containing unsaturated silicon and germanium atoms in the hope that these new systems will provide some unusual electronic properties that might give way to conjugated macromolecules incorporating double bonds in silicon and germanium.
