A Sonogashira cross-coupling/electrophilic cyclization tandem reaction strategy based on a copper-catalyzed system is developed, efficiently constructing benzofuran frameworks through consecutive reactions. This catalytic system does not require inert gas protection or intermediate separation and purification, making it simple to operate under mild conditions. Experimental results show that the reaction exhibits excellent substrate tolerance. Whether it is an electron-rich or electron- deficient ortho-iodophenyl ether, or structurally diverse phenylacetylene derivatives, the target products can be obtained in good to excellent yields. Moreover, the efficiency of this method provides a practical and green new approach for the synthesis of arylacetylene compounds.

Key words: Sonogashira cross-coupling, copper catalysis, tandem reaction, benzofuran derivative
