无机物负载无配体钯催化剂在Suzuki反应中的应用

The Application of Palladium Catalysts Supported on Inorganic Compounds Without Ligand in Suzuki Reaction

Suzuki偶联反应是生成联苯类化合物的重要反应之一。大多数Suzuki偶联反应是采用均相配体钯催化剂来催化反应，其优点是分散性好，催化效率高，但是存在催化剂反应后回收困难，重金属残留污染产物等缺点，负载钯催化剂已成为研发的热点。由于配体制备过程较长，负载困难，因此不采用配体，直接将钯负载于无机载体上，可以大大简化催化剂的制备过程。综述了以高比表面积的无机物作载体，在无配体条件下，负载钯的制备方法以及催化Suzuki反应的研究进展。

The Suzuki coupling reaction is the one of the most important methods for construction of biphenyl aromatic compounds The homogeneous palladium ligand catalysts are used for catalyzing the most of Suzuki coupling reactions with the advantages such as good dispersion and high catalysis efficiency, and the disadvantages such as difficult catalyst recycle and heavy metal residual. The loaded palladium catalyst has become a focus of research and development. Compared to the loaded ligand palladium catalysts, palladium catalysts supported on inorganic compounds without ligand will greatly simplify the preparation of catalyst because of the complicated preparation process of ligand and difficult loading. The research progress for the preparation and application of palladium catalysts supported on the inorganic materials with the high specific surface area without ligand have been reviewed.
