新型含中性吡咯配体稀土金属有机配合物的合成方法、成键及性能研究

含中性芳烃稀土金属有机配合物已有报道，但是含中性芳烃配体的稀土金属有机胺基、烃基配合物的合成及反应性研究较少。中性吡咯作为环戊二烯基配体的等电子体，与含环戊二烯基配体稀土金属有机配合物相比，含中性吡咯配体稀土金属有机配合物研究极少，含中性吡咯配体限制几何构型稀土金属胺基、烃基及氢化物的合成、成键及性能研究未见文献报道。本项目拟系统开展含中性吡咯配体限制几何构型稀土金属胺基、烃基及氢化物合成方法，成键及性能研究，探索出含中性吡咯配体限制几何构型稀土金属胺基、烃基等类型配合物的有效合成方法，研究配体取代基电子、立体因素对成键的影响，研究含中性吡咯配体限制几何构型稀土金属胺基配合物、烃基配合物与有机小分子的反应性及其在催化C-N、C-P、C-C键形成反应中的应用。通过项目研究可望探索出该类新型稀土金属有机配合物的合成方法，成键规律，新反应性及发展新型催化剂，为开发我国丰富稀土金属资源提供理论基础

Organo Rare-earth metal complexes containing neutral arene ligands have been reported. However, organo rare-earth metal amides, alkyls complexes with neutral arenes as supported ligands were less studied. Pyrrole, as an isoelectronic analogous to cyclopentadienyl anion, chemistry of organo rare-earth metal amides, alkyls and hydrides with the neutral pyrroles as supporting ligands in the constrained geometry architecture are scarely developed in comparison with that of organo rare-earth metal complexes with cyclopentadienyl ligands. This project aims to search for the synthetic methods, reactivity and property of organo rare-earth metal amides, alkyls, and hydrides with neutral pyrroles as supporting ligands in the constrained geometry architechture. The electronic and steric effects on the bonding of the neutral pyrroles with rare-earth metals, reactivity and catalytic applications for C-N, C-P and C-C bond formation of the novel rare-earth metal complexes with the neutral pyrroles in the constrained geometry architecture will also be studied. It is expected that the synthetic methods for the Pi-bonded neutral pyrroles as ligands, new reactivity and new catalysts for applications in organic synthesis will be developed with the accomplishment of the project.
