A Cu-mediated ligand-free arylation of NH-sulfoximines and sulfonamides by arylhydrazine hydrochlorides was herein demonstrated. The oxidative transformation provided an easy access towards N-aryl sulfoximines and sulfonamides in high yields (up to 93% yields) with broad functional groups tolerance (up to 36 examples). The protocol was proposed to take place through the free radical pathway based on the results of control reactions and EPR analysis.
Sulfonimidates: Useful Synthetic Intermediates for Sulfoximine Synthesis via C-S Bond Formation
Matos, Priscilla Mendon?a,Lewis, William,Moore, Jonathan C.,Stockman, Robert A.

Medicinally relevant sulfoximines are accessed from C-S coupling of sulfonimidates and commercially available organomagnesium reagents. Sulfonimidates are conveniently synthesized by oxidative alkoxylation of readily available sulfinamides. This constitutes a general C-S coupling approach for the synthesis of sulfoximines.
Copper-catalyzed ultrasound-expedited N-arylation of sulfoximines using diaryliodonium salts
Vaddula, Buchireddy,Leazer, John,Varma, Rajender S.
supporting information; experimental part, p. 986 - 990 (2012/05/20)
An ultrasound-accelerated route for an expeditious N-arylation of NH-sulfoximines is described that involves the use of diaryliodonium salts in aqueous polyethylene glycol-400 and copper(I) bromide as catalyst at room temperature. The high yields of the p
