ABSTRACT In this study, we developed a metal‐free, intermolecular C(sp 2 )–H imidation of anilines and phenols using sulfonimides, yielding isolable aryl sulfonimides under facile conditions. MesI(OAc) 2 and HNTs 2 combine to produce an O‐bridged I(III)‐NTs 2 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.
