Herein we report a highly efficient method for nickel-catalyzed C−N bond formation between sulfonamides and aryl electrophiles. This technology provides generic access to a broad range of N-aryl and N-heteroaryl sulfonamide motifs, which are widely represented in drug discovery. Initial mechanistic studies suggest an energy-transfer mechanism wherein C−N bond reductive elimination occurs from a triplet excited NiII complex. Late-stage sulfonamidation in the synthesis of a pharmacologically relevant structure is also demonstrated.
