A novel copper-catalyzed N-arylation/alkylation of sulfoximines with acyl peroxides as aryl/alkyl source was developed. This approach undergoes a radical pathway, representing an alternative complement to construct N-arylated/alkylated sulfoximines.

A transition-metal-free novel route to access N-(o-halo)arylsulfoximines/sulfonimidamides is achieved by the reaction of sulfoximine/sulfonimidamide, aryne precursor, and CCl4/CBr4 in the presence of KF/18-crown-6. The in situ generated benzyne intermediate (from silyl aryl triflate) reacts with the nucleophile (sulfoximine/sulfonimidamide) and halide source (CCl4/CBr4) to yield the product in moderate
