Bis(trimethylsilyl)sulfur diimide is the organosulfur compound with the formula S(NSiMe3)2 (Me = CH3). A colorless liquid, it is a diaza analogue of sulfur dioxide, i.e., a sulfur diimide. It is a reagent in the synthesis of sulfur nitrides. For example, it is a precursor to C2(N2S)2.
Bis(trimethylsilyl)sulfur diimide is prepared by the reaction of thionyl chloride and sodium bis(trimethylsilyl)amide: SOCl2 + 2 NaN(SiMe3)2 → S(NSiMe3)2 + 2 NaCl + O(SiMe3)2
