A hydrazide catalyst is introduced for the late-stage halogenation of peptides, drugs and (hetero)aromatics with high efficiency and selectivity. The active site comprises the hydrazide group attached to a sulfonamide moiety, which facilitates the acceptance as well as delivery of halonium species from the N-halosuccinimide source to the substrates, thus featuring a cooperative interaction.
