A RhIII‐catalyzed addition of arylCH bonds to nitrosobenzenes, followed by cleavage of the resulting hydroxylamines in situ, has been reported. Different directing groups, such as N‐based heterocycles and ketoximes, can be used in this CHamination process, providing valuable diarylamines in excellent yields. Most importantly, this process provides a new method for attaching arylamine groups to
