Palladium-Catalyzed/Norbornene-Mediated <i>ortho</i>-Amination/<i>N</i>‑Tosylhydrazone Insertion Reaction: An Approach to the Synthesis of <i>ortho</i>-Aminated Vinylarenes

ortho-Aminated vinylarene derivatives were obtained via a reaction of aryl iodides, N-benzoyloxyamines, and N-tosylhydrazones. This approach involves a palladium-catalyzed, norbornene-mediated ortho-amination/N-tosylhydrazone insertion reaction. In this transformation, one C–N bond and one C–C bond are formed and an amine group is introduced at the ortho position successfully.
