Tetraalkylammonium N-chloro-p-toluenesulfonamides were prepared from chloramine T and tetraalkylammonium chlorides as a substance corresponding to anhydrous chloramine T, and found to give rise to the effective tosylimination of phosphorus compounds and diaryl sulfides.
A new practical procedure of imination for sulfide has been developed. The treatment of (N-tosylimino)-phenyl-λ3-iodane, PhINTs, with various sulfides in the presence of a catalytic amount of I2 under metal-free conditions affords the corresponding N-tosylsulfilimine compounds with moderate to good yields. This facile transfer procedure of the sulfonylimino group can also be applied to triphenylphosphine

Abstract A number of N-sulfonylsulfilimines have been prepared through a novel way for the reaction of iodosobenzene diacetate with sulfides and sulfonamides under mild conditions.

While excellent methods exist for the oxidation of sulfides to sulfoxides R1R2S-->R1R2SO, the azaversion of this atom transfer redox process, i.e., R1R2S-->R1R2S=N-SO2R3, has been less reliable. In sulfilimine synthesis, sulfoxide has been an inevitable byproduct in all cases to date, and the yields of sulfilimine have varied widely. A nearly ideal procedure for the sulfide to sulfonyl sulfilimine
