tertiary amine and ketone components of 1‐carbonyl‐substituted anilines undergo [1,2] and [2,3] Stevens rearrangement reactions, triggered by a C4F9 radical, formed from electron donor–acceptor complexes. This approach enables the formation of a quaternary ammonium salt and thus a Stevens rearrangement to afford indolin‐3‐ones under mild conditions.
