The palladium-catalyzed carbonylation coupling reaction of ethynylferrocene with aryl iodides under an atmosphere of carbon monoxide is a convenient, effective, and versatile method for the synthesis of aryl ferrocenyethynyl ketones. Likewise, the palladium-catalyzed carbonylation coupling-annulation reaction of ethynylferrocene with substituted 2-iodophenol gives 2-ferrocenyl-4H-chromen-4-ones. The reactions were performed in short time and gave the products in good yield.
