mild catalytic system to access diversely functionalized benzylic sulfonamides has been developed. Palladium-catalyzed alpha-arylation by Negishi cross-coupling of sulfonamide-stabilized anions and a wide range of aryl iodides, bromides, and triflates constitutes a practical strategy for the synthesis of various benzylic sulfonamides.
