A novel copper‐catalyzed CH arylation of heteroarenes with anilines by an in situ diazonium reaction is established by using silver nitrite (AgONO) as an unconventional nitrosating reagent under acid‐free conditions. It provides a complementary approach for the CH arylation of electron‐richheteroarenes with aromatic amines affording a variety of heterobiaryls in moderate to good yields.
