钯纳米粒子@超顺磁性Fe3O4催化的Heck偶联反应
Nano-palladium @superparamagnetic Fe3O4 as catalyst for Heck coupling reaction
摘要
Abstract
In this work, a simple way to combine Pd° with Fe3O4 nanoparticles (NPs) is developed. Firstly, PdClf was immobilized on the cationic Feg O4 colloids via electrostatic interaction. Further reduction of these PdCl4-/ Fe3O4 was resulted in Pd°@Fe3O4 NPs. These superparamagnetic NPs supported Pd° showed high efficiency toward Heck reactions. After the reaction, the catalyst could be simply recycled by permanent magnet. This Pd°@Fe3O4 catalyst could be reused for 5 times without significant loss in catalytic activity and showed high efficiency toward Heck coupling for various aryl halides.关键词
