Thermal Nickel‐Catalyzed N ‐Arylation of Sulfonimidamides With (Hetero)aryl Chlorides Enabled by PAd‐DalPhos Ligation

Reported herein is the first nickel‐catalyzed N ‐arylation of sulfonimidamides at the imine position employing (hetero)aryl chloride reaction partners with useful substrate scope. Such otherwise challenging transformations are enabled under mild conditions and in synthetically useful isolated yields by use of a PAd‐DalPhos/Ni catalyst system, including N ‐arylation of the active pharmaceutical ingredient chlorpromazine.
