Palladium Supported on Commercial Fumed Silica as Sustainable Catalyst for Suzuki-Miyaura Coupling Reactions
- 24 Downloads
Palladium nanocatalysts supported on commercial fumed silica were synthesized via a convenient liquid method without any external reductant or surfactants. The catalysts were characterized by inductively coupled plasma-mass spectrometry, X-ray powder diffraction and the transmission electron microscope analysis. Then it was applied for Suzuki-Miyaura cross-coupling reactions. It was found that a number of aryl halides were efficiently catalyzed using these catalysts in aqueous-ethanol under relatively mild condition within 0.5h. Further study showed that the catalyst could be recycled up to 10 times without loss of activity.
