无机物载体负载钯催化Suzuki偶联反应研究进展

Suzuki芳基偶联反应是构建联苯芳烃和多联苯芳烃结构单元的重要反应之一。传统的Suzuki偶联反应的催化剂多数是均相催化剂,催化活性很高,但存在催化剂回收困难、污染产品等缺点。固定化技术可有效地解决上述问题,已成为Suzuki偶联反应的催化剂研发的热点。综述了近些年来以无机碳、金属氧化物、多孔分子筛等无机材料为载体负载钯催化Suzuki偶联反应的最新进展。

The Progress in Study on Suzuki Coupling Reaction over Palladium Catalysts Supported on Inorganic Compounds

The Suzuki aromatic coupling reaction is one of the most important methods in the construction of biphenyl and multi-phenyl structure unit. The traditional catalysts for Suzuki coupling reactions is almost homogeneous catalysts with the high catalysis activity,but there are a few disadvantages such as difficult separation and reuse of catalysts from reactive system and polluting products. The above problems are efficiently solved by the fixed technology which has become the hot-spot of research on Suzuki coupling reaction catalysts. The latest progress of Suzuki coupling reaction over palladium catalysts supported on inorganic materials including inorganic carbon, metal oxide, porous zeolite are summarized.
