Rh‐Catalyzed Diarylamine Synthesis by Intermolecular C–H Amination of Heteroarylarenes

Abstract A novel and efficient Rh‐catalyzed intermolecular C–H amination of heteroarylarenes with aryl azides has been developed. This procedure does not require an oxidant, releases N2 as the only byproduct, and provides an efficient approach to diarylamines with broad functional‐group tolerance.
