N-Methylimidazole functionalized carboxymethycellulose-supported Pd catalyst and its applications in Suzuki cross -coupling reaction

In this paper, N-Methylimidazole functionalized carboxymethylcellulose-supported palladium nanoparticles (CMC-NHC-Pd) was synthesized and characterized by TEM, SEM, EDX, CP/MAS C-13 NMR, FT-IR, TGA, XRD, and XPS analysis. The prepared nanoparticles can be used as an environmentally-friendly and trifunctional catalyst. The well-designed CMC supported palladium nanoparticles catalyst with poly dentate ligands is also stable and efficient for Suzuki cross-coupling reactions under mild conditions through the cooperative interaction of trifunctional capturing sites with palladium, -COO-, -OH and N-Methylimidazole. This catalyst can be readily recovered by a few cycles of simple filtration. This work proposes a plausible trifunctional catalyst complex. (C) 2016 Elsevier Ltd. All rights reserved.
