无配体负载钯催化Suzuki偶联反应的研究进展

金属钯催化的Suzuki偶联反应是碳一碳偶联反应中的最重要的反应之一。传统的均相催化体系具有很多的不足，如产物与催化剂不易分离、原料价格昂贵、催化剂不能重复使用等，而使用无配体负载钯的催化剂可有效地解决上述问题。综述了近些年来无配体材料负载钯催化Suzuki偶联反应的研究进展，载体包括碳材料、多孔分子筛、水滑石、高分子材料、金属氧化物、硅藻土、纤维素、磷灰石和氟硅胶等。

The Research Progress in Suzuki Coupling Reactions Catalyzed by Supported Ligand-Free Palladium Catalysts

The Suzuki coupling reactions catalyzed by metal palladium catalysts is one of the most important reactions in C-C coupling reaction.There are some disadvantages in traditional homogeneous catalysts,such as difficult separation and recycle of catalysts and product,expensive cost of raw materials.The problems mentioned will be effectively solved by use of the supported ligand-free palladium catalysts.In this paper,the research progress in Suzuki coupling reactions catalyzed by supported ligand-free palladium catalysts on different carriers have been reviewed,such as carbon materials,porous molecular sieve,hydrotalcite,polymer materials,metal oxide,diatomite,cellulose,apatite and fluorine silica gel.
