The polysulfonylamines bis(methylsulfonamido) sulfone and bis(trifluoromethylsulfonamido) sulfone

J. Taraba and Z. Zák

Abstract: Bis(methylsulfonamido) sulfone, C₂H₈N₂O₆S₃ or SO₂(NHSO₂CH₃)₂, was synthesized from imidobis(sulfonyl chloride), HN(SO₂Cl)₂, and bis(trimethylsilyl)methane, CH₂[Si(CH₃)₃]₂, in chlorotrimethylsilane solution. In the solid state, there are two independent molecules linked by two N-HO hydrogen bridges into infinite chains parallel to the b axis. The central S atoms of the independent molecules each lie on a twofold axis. Bis(trifluoromethylsulfonamido) sulfone, C₂H₂F₆N₂O₆S₃ or SO₂(NHSO₂CF₃)₂, was formed by the reaction of trichlorophosphazosulfuryl trifluoromethane, Cl₃PNSO₂CF₃, with fluorosulfonic acid, FSO₃H. The molecules are connected by bifurcated N-HO bridges into infinite layers parallel to the [001] plane. The central S atom lies on a twofold axis.

Formula: C₂H₈N₂O₆S₃ and C₂H₂F₆N₂O₆S₃
