The expedient and efficient copperpowdercatalyzeddirectring-openingarylation of benzazoles with aryliodides in polyethyleneglycol that proceeds in the absence of an added ligand has been developed. The protocol provides facile access to 2-(arylthio)anilines and 2-phenoxyanilines in high yields with a wide tolerance of functional groups. Transmission electron microscopy confirmed that the active
