Synthetic, Mechanistic, and Catalytic Actinide Organometallic Chemistry

该奖项来自无机、生物无机和有机金属化学项目，为锕系元素和镧系元素的有机金属化学研究项目提供了新的支持。锕系元素包括非常重的金属，如铀，而镧系元素，也被称为“稀土”，包括不太熟悉的金属，如钕和钇，它们在激光中有实际用途。目前有机金属化学家对这些元素非常感兴趣，因为人们发现它们能以不同寻常的合成方式与有机化合物发生反应。该项目是对f族元素的有机金属化合物的化学性质和反应机制的广泛探索。目标是发展和理解基于这些金属离子的不寻常的结构和热力学性质和反应性的新化学。要研究的化学转化（包括化学计量和催化）包括以金属为中心的H-H、C-H和C-C活化过程，以及烯烃的插入、修饰和低聚过程。重点还将放在具有新型配体和新形式氧化态的配合物的合成和性质上。长期目标是了解控制这些元素化学反应性的结构和电子因素，并利用刺激新的或增强的反应性模式的特征。

This award from the Inorganic, Bioinorganic and Organometallic Chemistry Program provides renewed support for a project concerned with the organometallic chemistry of the actinide and lanthanide elements. The actinide elements include the very heavy metals, such as uranium, whereas the lanthanide elements, also known as the "rare earths," include the less familiar metals, such as neodynium and yttrium which find practical uses in lasers. These elements are of substantial current interest to organometallic chemists because they have been found to react in unusual and synthetically useful ways with organic compounds. The project is a broad exploration of the chemical properties and mechanisms of reactions of organometallic compounds of the f-group elements. The goal is to develop and understand new chemistry based on the unusual structural and thermodynamic properties and reactivity of these metal ions. Chemical transformations (both stoichiometric and catalytic) to be studied include metal-centered H-H, C-H and C-C activation processes, as well as olefin insertion, modification and oligomerization processes. Emphasis will be placed also on the synthesis and properties of complexes having new types of ligands and new formal oxidation states. The long range goal is to understand those structural and electronic factors which control chemical reactivity of these elements, and to capitalize on features which stimulate new or enhanced modes of reactivity.
