新型PNP配体的设计、合成及其配合物在催化C-C偶联反应中的应用

本项目合成氨基取代的二膦类PNP配体，与Ni，Pd，Pt等金属盐反应制备相应配合物，表征所得配合物的结构。用所得配合物催化Heck，Suzuki等偶联反应。探索配合物的结构和催化效率之间的关系。进一步设计合成新型PNP型配体，开发一类新型高效催化剂，并完善合成方法。

This project is planed to synthesis a group of PNP type ligands in which amino groups are substituted by diphosphines, and carry out the reactions of these ligands with Ni, Pd and Pt salts. The structures and the catalytic properties on coupling reactions such as Heck and Suzuki reactions of the resulted complexes will be determined. The relationship between the structures of complexes and the catalytic efficiency will be discussed. Based on these researches, some new PNP type ligands will be designed and synthesized. A family of high effective catalysts will be discovered. The synthetic methods will be improved thereafter.
