N-heterocyclic arenesulfonamides (NHAS) was performed using experimental and theoretical methods. Ten newexamples of NHAS with pyridine and thiazole N-heterocycles were synthesized. X-ray diffraction studies on one of the compounds suggested that the sulfonimide form is preferred; the molecule exists as a dimer due to two strong intermolecular hydrogen bonds. The possibility of sulfonamide (N-sulfonylamine) sulfonimide
