Diaryliodonium salts have low toxicity and good stability, and their mediated reactions often have advantages of mild reaction conditions and high selectivity. They have received extensive attention and have been widely used as arylating agents in organic synthesis. A simple and efficient method for the synthesis of 2-arylbenzothiazole derivatives via copper-catalyzed C-H direct arylation of benzothiazoles with diaryliodonium salts as electrophilic arylating reagents was developed. This method shows wide range of substrates, good group tolerance, simple operation and high product yields.

Key words: benzothiazole, arylation, diaryliodonium salt, cross coupling, C-H activation
