Suzuki-Miyaura反应是一类具有工业化应用前景的C-C键合成反应。反应多数是在均相金属钯配体催化剂催化下完成。均相催化具有催化效率高、产品选择性好等优点,但催化剂回收困难,增加了反应成本,限制了其应用。非均相金属钯配体催化剂是将均相金属钯配体催化剂固载到载体上,使其在不影响反应活性和选择性的同时,实现循环使用,已成为Suzuki-Miyau-ra反应的研究热点。对几年来以有序介孔材料MCM-41和SBA-15、无机载体SiO2和Al2O3、聚苯乙烯和聚乙二醇等合成材料以及天然高分子材料为载体,制备非均相金属钯配体催化剂的方法及其催化性能进行了综述。
Suzuki-Miyaura reaction is a type of C-C bond reaction with industrial application prospect. Most of the reaction is carried out under the catalysis of homogeneous metal palladium ligand catalyst. Homogeneous catalysis has the advantages of high catalytic efficiency and good product selectivity. However, catalyst recovery is difficult, which increases the reaction cost and limits its application. Heterogeneous metal palladium ligand catalyst is a homogeneous metal palladium ligand catalyst is immobilized on the carrier, so that it does not affect the reactivity and selectivity of the recycle, has become a Suzuki-Miyau-ra reaction Hot spots. In recent years, mesoporous materials MCM-41 and SBA-15, inorganic carriers SiO2 and Al2O3, polystyrene and polyethylene glycol and other synthetic materials and natural polymer materials as a carrier, preparation of heterogeneous metal palladium ligand Catalyst method and its catalytic performance are reviewed.
