Abstract

(Me₃Si)₂NS₃N(SiMe₃)₂ has been prepared by two different, but related synthetic routes: The reactions of (a) (Me₃Si)₂NLi with SCl₂ and elemental sulfur, and (b) (Me₃Si)₂NH with S₂Cl₂. The reaction products were identified by elemental analysis, mass spectroscopy, and by ¹H, ¹³C, and ¹⁴N NMR spectroscopy. (Me₃Si)₂NS₃N(SiMe₃)₂ reacts with SCl₂ and SO₂Cl₂ to produce S₄N₂ in good yield (72.5%).
