N-Trifluoromethylsulfonyl-S-trifluoromethyl-S-arylsulfoximides were obtained by the reaction of the sodium salts of S-trifluoromethyl-S-arylsulfoximides with the anhydride or chloride of trifluoromethanesulfonic acid.In electronic nature the CF3S(O)=NSO2CF3 group is a "superstrong" electron-withdrawing substituent, which corresponds to the effect of the two nitro groups at the ortho and para positions to the reaction center.The dimethylaminoazo dye with the CF3S(O)=NSO2CF3 substituent at position 4 exhibits negative halochromism.
