I n 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
