Dinuclear palladium complexes formed by a chelate-bridging ligand showed β-selectivity in the direct arylation of furans with iodoarenes. In contrast, the arylation using PPh3 or bpy as ligands gave α-arylfurans as major products. The arylation can be applied to several furans bearing functional groups except electron-withdrawing groups.
