Herein, we report an unprecedented aerobic copper-catalyzed [3+2] annulation reaction of diarylamines with indoles, which allows direct access to novel 2-diarylaminoindolo[2,3- b ]indoles, a class of potential photoelectric device molecules. The developed transformation proceeds with broad substrate...
