Metal‐Free Intermolecular C–H Imidation of Anilines and Phenols With Sulfonimides
In this study, we developed a metal-free, intermolecular C(sp<sup>2</sup>)-H imidation of anilines and phenols using sulfonimides, yielding isolable aryl sulfonimides under facile conditions. MesI(OAc)<sub>2</sub> and HNTs<sub>2</sub> combine to produce an O-bridged I(III)-NTs<sub>2</sub> adduct, which is stabilized via π-π stacking and aids efficient sulfonimide transfer. The necessary mild conditions and broad functional group tolerance of this transformation establish a sustainable C─N bond formation approach to synthesizing various aryl sulfonimides via hypervalent iodine-mediated C─H imidation.
