Heterogeneous PdO@SNP Catalyst for Decarbonylation, Suzuki and Sonogashira Cross-coupling Reactions in Aqueous Medium. |
| 초록 |
A sonochemical method has been employed for the synthesis of heterogeneous PdO@SNP catalyst. Well-dispersed palladium oxides nanoparticles (PdO) were doped on surface of silica nanoparticles (SNP) at room temperature and atmospheric pressure with minimum reaction time. The silica nanoparticles as a support were fabricated with nano-sized PdO by water-oil emulsion method. PdO coordinated with silica nanoparticles (PdO@SNP) was applied as a nanocatalyst for decarbonylation, Sonogashira and Suzuki coupling reactions. Moreover, the catalyst has shown high catalytic activity and selectivity than unsupported PdO nanoparticles for all reactions. This silica-supported Pd catalyst could be easily recovered by simple filtration of the reaction mixture. Also, filtrated PdO@SNP catalyst was reused for all transformations for several times keeping its catalytic activity. |
