Suzuki coupling of iodo and bromoarenes catalyzed by chitosan-supported Pd-nanoparticles in ionic liquids

• Pd-NPs on chitosan have been used for the first time in Suzuki coupling in ionic liquids.
• In molten tetrabutylammonium bromide biaryls have been obtained in high yields.
• A low catalyst loading is used and the catalyst can be recycled without deactivation.
• Hot-filtration test confirmed a heterogeneous catalysis.

Palladium nanoparticles supported on chitosan (Pd-NPs@Chitosan) have been used for the first time in Suzuki cross coupling of bromo and iodoarenes carried out in ionic liquids. The reaction proceeded smoothly in molten tetrabutylammonium bromide (TBAB) affording unsymmetrical biaryls in good to excellent yields. A low catalyst loading (0.1%) is used and the catalyst can be recycled without deactivation.
