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 Ni II complex. Late‐stage sulfonamidation in the synthesis of a pharmacologically relevant structure is also demonstrated.
