초록

An efficient synthetic method to access ethyl arylpropiolates has been developed; it involves a palladium-catalyzed cross-coupling reaction between a wide range of aryl iodides and lithium tetrakis(ethoxycarbonylethynyl)indates (0.35 equiv) generated in situ from indium trichloride and alkynides obtained from ethyl propiolate and n-butyllithium.
