- Study on the reactions of fluoroalkanesulfonyl azides with indole derivatives
-
The reactions of fluoroalkanesulfonyl azides 1 with different indole derivatives have been studied in detail. Treatment of 1 with equimolar amount of 1,3-dimethylindole 3 in 1,4-dioxane at room temperature afforded 2-(1,3-dimethyl-1,3-dihydro-indolinylidene) fluoroalkanesulfonylimines 5 in moderate to good yields. However, under the same reaction conditions, in the case of 1 with 1,2-dimethylindole 4, the corresponding 2-fluoroalkanesulfonyl (1,2-dimethyl-1H-indol-3-yl)-amide 6 was obtained in moderate yields. In addition, the reactions of 1 and indole 7 gave different products under different conditions. Possible mechanisms of these reactions were proposed.

- Unexpected formation of the novel fluorinated diazenes
-
Fluoroalkanesulfonyl azides reacted with morpholine giving unexpectedly N-fluoroalkanesulfonyl-N-morpholino diazenes, which were fully characterized by using spectral methods and X-ray diffraction analysis.

- Study on the reactions of fluoroalkanesulfonyl azides with pyridine and its derivatives
-
The thermal reactions of fluoroalkanesulfonyl azides R(f)SO2N3 1 with pyridine and its derivatives have been investigated in detail. In many cases, N-fluoroalkanesulfonyl pyridinium imides Y+-N'SO2R(f) (Y: pyridine, 3- picoline, 3,5-lutidine and quinoline) and the hydrogen abstraction products R(f)SO2NH2 were obtained. 2-Picoline and 4-picoline reacted with 1 to give R(f)SO2NH2 exclusively. Interestingly, in the reaction of azides 1c IC2F4OC2F4SO2N3 with 4-picoline or quinoline, the ω-iodine of the azide was substituted to form ArC2F4OC2F4SO2NH2.

-
Reaction of perfluoroalkanesulfonyl amides with dialkyl sulfides or sulfoxides in the presence of stoichiometric amounts of lead tetra-acetate gave N-perfluoroalkanesulfonyl sulfilimines or N-perfluoroalkanesulfonyl sulfoximides, respectively, in moderate to good yield. - Keywords: Synthesis; Perfluoroalkanesulfonyl amides; N-perfluoroalkanesulfonyl sulfilimine; Sulfoximide
