A regioselectivedirectarylation of arenes and olefins at the ortho position is reported. The key to the high selectivity is the appropriate choice of diaryliodonium salts as the arylating reagent in the presence of a cationic iridium(III) catalyst. The coordination of the metal with an oxygen atom or a nitrogen atom and subsequent C–H activation allows for directarylation with coupling partners
