Organo-silane Based N-Heterocyclic Carbene (NHC) Palladium Catalyst for C-C Coupling Reactions |
| 초록 |
Silica-supported N-heterocyclic carbene (NHC) palladium catalyst was prepared. Ionic liquid was coordinated with palladium acetate to obtain an organosilane-based bidentic NHC-Pd complex. The organosilane-based bidentic NHC-Pd complex was immobilized on silica particles by covalent bond (NHC-Pd/silica). The catalyst proved to be highly active for general C-C coupling reactions such as Suzuki, Heck and Sonogashira (Cu free) reaction. This NHC-Pd/Silica catalyst was confirmed to be an efficient catalyst for each of the reaction under mild conditions. Moreover, the catalyst could be recycled by simple filtration without significant loss of its catalytic activity. |
