Herein, we developed a mild and efficient palladium-catalyzed carbonylative Sonogashira coupling of aryl thianthrenium salts with aliphatic alkynes benzyl acetylene toward alkynones furanones. Various desired products were prepared in good yields broad functional group tolerance including the bromide group. In case using acetylene, corresponding furanones can be obtained under same conditions two molecules CO inserted.
