A mild and efficient protocol for the copper(I)-catalyzed C4-H sulfamidation of 1-naphthylamine derivatives with diphenylsulfonimide (NHSI) was explored at room temperature, affording the desire produces in moderate to good yields. The control experiments indicated that this visible-light-promoted reaction might proceed via a single-electron-transfer process. In addition, preliminary DFT studies for the intermediates in the catalytic cycle were also explored, indicating that the C4 site in the naphthyl ring is the most likely electrophilic reactive site and providing some exact basis for the plausible mechanism.

N -Sulfonylformamidines were synthesized from N -sulfonylsulfonamides by reacting with p -toluenesulfonyl chloride (TsCl) and N, N - disubstituted formamides. In this reaction, it was expected that mixing TsCl with the N, N -disubstituted formamide would generate an iminium salt (Vilsmeier reagent). The reaction avoids the use of metal catalysts and hazardous reagents, and the desired N -sulfonylformamidines were obtained in 60% to quantitative yields.
N-bromo-(4-methylphenyl) sulfonimide: A mild and efficient reagent for oxidative deoximation of oximes under microwave irradiations
Manesh, Abbas Amini,Khazaei, Ardeshir
experimental part, p. 624 - 626 (2012/01/03)
Aldoximes and ketoximes are converted to the parent carbonyl compounds in good yields when treated with N-bromo-(4-methylphenyl) sulfonimide (2), under microwave irradiations. The simple work-up minimizes the loss of product and oximes have been selectively oxidized in the presence of alcohols and alkenes.
