Organoboron/iodide-catalyzed photoredox N -functionalization of NH-sulfoximines/sulfonimidamides.

An aminoquinolate diarylboron (AQDAB) and tetrabutylammonium iodide (TBAI) co-catalyzed photoredox process for N -functionalization of NH-sulfoximines/sulfonimidamides has been successfully developed. This protocol can afford the corresponding N -sulfenylated and N -phosphonylated products in good to excellent yields under conditions without metallic (photo)catalysts, external oxidants, or acidic/basic additives. A wide range of functional groups are tolerated, and the N -phosphonylated products of NH-sulfonimidamides have been reported for the first time.
