摘要：

Cyclodehydration of various alpha-aryloxy ketones proceeded to give various multisubstituted benzofurans by using an Ir(III) catalyst, which was prepared from [Cp*IrCl2](2), AgSbF6, and Cu(OAc)(2). The use of the cationic iridium complex with a carboxylate salt realized the efficient transformation at ambient temperature.
