Double role: A traceless directinggroup also acts as an internal oxidant in a novel RhIII‐catalyzed protocol developed for the synthesis of ortho‐alkenylated tertiary anilines (see scheme). A five‐membered cyclometalated RhIII complex is proposed as a plausible intermediate and confirmed by X‐ray crystallographic analysis.
