Cyclodehydration of various -aryloxy ketones proceeded to give various multisubstituted benzofurans by using an Ir(III) catalyst, which was prepared from [Cp IrCl AgSbF and Cu(OAc) The use of the cationic iridium complex with a carboxylate salt realized the efficient transformation at ambient temperature.
