Palladacycle‐Catalyzed Carbonylation of Aryl Iodides or Bromides with Aryl Formates

Abstract An efficient palladacycle‐catalyzed aromatic carbonylation reaction of aryl formates with aryl iodides or bromides has been developed. Commercially available and easily prepared aryl formates were employed as carbonyl sources without the use of external carbon monoxide. The present catalytic system shows broad functional group tolerance and affords aryl benzoate derivatives in good to excellent yields.
