摘要：

An efficient copper-, phosphine ligand- and palladium-free indium-catalyzed Sonogashira coupling reaction has been developed in the presence of 1 mol% indium trichloride. Coupling of various aryl halides with terminal alkynes afforded the corresponding aryl alkynes in moderate to excellent yields.
