An efficient copper-catalyzed radical decarboxylative imidation reaction is presented. This strategy is carried out through the copper(i)-catalyzed decarboxylative C(sp(3))-N and C(sp(2))-N coupling of carboxylic acids with N-fluoroarylsulfonimides. The reaction shows good functional group tolerance and it provides a new approach for decarboxylative imidation. Preliminary mechanistic studies of this transformation suggest an involvement of N-centered radical species.
