Abstract:

In this paper, Novel Magnetically Chitosan@N-Heterocyclic Carbene-Palladium (NHC-Pd) Coated Multi-Walled Carbon Nanotube (MWCNTs) was synthesized in three steps: 1. The reaction of Chitosan, glyoxal and formaldehyde for synthesis of Chitosan@imidazol, 2. Synthesis of magnetic functionalized-MWCNTs and 3. The esterification reaction via the reaction of hydroxyl and carboxylic acid groups of Chitosan@imidazol and magnetic functionalized-MWCNTs respectively, and followed with the attachment of palladium chloride to compose of novel NHC ligand for the first time. Catalytic studies of Magnetic Chitosan@ NHC-Pd Coated MWCNTs for the Suzuki cross-coupling reaction of various aryl halides with aryl boronic acids have been evaluated in the ethanol��?water solution. In general, our new catalyst showed superior reactivity for this model reaction. Moreover, the heterogeneous catalyst can be easily recovered by external magnet field and reused for subsequent use without any significant loss in catalytic activity
