n this paper, Novel Magnetically [email protected]

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 [email protected],

2. Synthesis of magnetic functionalized-MWCNTs and

3. The esterification reaction via the reaction of hydroxyl

and carboxylic acid groups of [email protected] 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 [email protected] 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
