Iron‐Catalyzed Electrophilic Amination of Sodium Sulfinates with Anthranils

Abstract A practical method for the synthesis of N ‐(2‐carbonylaryl) benzenesulfonamides via an iron‐catalyzed electrophilic amination of sodium sulfinates with anthranils is described. This redox‐neutral transformation has high atom efficiency and is achieved under simple and mild reaction conditions. A wide range of anthranils and sodium sulfinates were compatible in this transformation. Moreover, the synthetic potential of this methodology was further demonstrated by the synthesis of various useful N‐heterocycles and derivatives.
