The first palladium-catalyzed esterification of carboxylicacids with aryl iodides is described. A palladium-based catalytic system consisting of IBnF (1,3-bis((pentafluorophenyl)methyl)imidazole-2-ylidene) ligand was found to significantly accelerate the aryl–O bond-forming esterification reaction. A series of aryl iodides and carboxylicacids undergoes a palladium-catalyzed coupling reaction to provide
