New tris(dimethylamino)sulfonium (TAS) salts containing [ArNSN]- anions were synthesized. These air-sensitive compounds were characterized as Z isomers, revealing unique S-N bond lengths indicative of thiazylamide structures.

Area of Science:

  • Inorganic Chemistry
  • Organosulfur Chemistry
  • Computational Chemistry

Background:

  • Tris(dimethylamino)sulfonium (TAS) salts are known for their utility as non-nucleophilic cations.
  • Sulfurdiimides are versatile precursors in sulfur-nitrogen chemistry.
  • The synthesis and characterization of novel sulfur-nitrogen anions present significant chemical interest.

Purpose of the Study:

  • To synthesize novel air-sensitive tris(dimethylamino)sulfonium (TAS) salts of [ArNSN]- anions.
  • To elucidate the structural and bonding properties of the [ArNSN]- anion.
  • To compare experimental findings with theoretical calculations.

Main Methods:

  • Synthesis of [ArNSN]- anions from sulfurdiimides using tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF).

  • Low-temperature X-ray crystallography for structural determination.
  • Computational studies including restricted Hartree-Fock (RHF), density functional theory (DFT), and Møller-Plesset second-order (MP2) calculations.

    • Main Results:

    • Successful preparation of air-sensitive, thermally unstable TAS salts of [ArNSN]- anions.
    • X-ray crystallography confirmed the Z isomer configuration of the [ArNSN]- anion.
    • Observed distinct S-N bond lengths (terminal: 144.2–147.9 pm, internal: 158.3–160.3 pm) suggest a thiazylamide structure with a formal S≡N triple bond.

    Conclusions:

    • The [ArNSN]- anion represents a rare thiazylamide species with a highly polarized S≡N triple bond.
    • Experimental structural data aligns with theoretical bonding models.
    • The synthetic route provides access to novel sulfur-nitrogen compounds for further investigation.
