Palladium-catalyzed triple coupling of 2-iodoanisoles with aryl iodides to access 6H-dibenzopyrans

A palladium-catalyzed triple coupling of 2-iodoanisoles with aryl iodides has been developed. 3-Methyl-2-pyridone was used as a ligand to accelerate the cross-coupling and suppress the homo-coupling of 2-iodoanisoles. A variety of 6H-dibenzopyran derivatives can be prepared by this method.
