A novel and efficient pathway for the generation of 3-(benzofuran-3-ylmethylene)benzofuran-2(3H)-ones via a palladium-catalyzedcarbonylativereaction of 2-alkynylphenol with carbon monoxide is described. The reaction proceeds through a double insertion of triple bonds during the reaction process. The products are obtained in good yields with high selectivity. A one-pot synthesis starting from 2-iodophenol
