Dual responsive PdNPs-SBA-15-PNIPAM/PMAA as a versatile and heterogeneous green nanocatalyst for the Suzuki-Miyaura coupling reactions in the aqueous medium |
| 초록 |
The Suzuki coupling reaction catalyzed palladium nanoparticle is one of the most promising and adaptable methods for forming C-C bonds in the field of pharmaceutical and organic chemistry. To develop a green and cost-effective platform for cross-coupling reactions, dual (temperature and pH)-responsive poly (N-isopropyl acrylamide-co-methacrylic acid) functionalized SBA-15 was synthesized by using free radical polymerization by using the initiator potassium persulfate and decorated with palladium nanoparticles (PdNPs-SBA-15-PNIPAM/PMAA). The catalyst displayed swelling behaviors at low temperatures (＜ 32 °C) and high pH (＞ 4), but exhibited deswelling behaviors at high temperatures (＞ 32 °C) and low pH (＜ 4). The resultant PdNPs-SBA-15-PNIPAM/PMAA catalyst was used for the Suzuki coupling reaction in aqueous medium at room temperature. The catalyst was successfully recovered from the reaction mixture and could be reused without any loss of catalytic activity. |
