Bis(trimethylsilyl) sulfide is the chemical compound with the formula ((CH3)3Si)2S. Often abbreviated (tms)2S, this colourless, vile-smelling liquid is a useful aprotic source of “S2-“ in chemical synthesis.
Additional recommended knowledge
((CH3)3Si)2S must be protected from air because it hydrolyzes readily:
(tms)2S is primarily used to convert oxides and chlorides into the corresponding sulfides. This transformation exploits the affinity of silicon(IV) for oxygen and halides. An idealized reaction is:
((CH3)3Si)2S reacts exothermically with water, releasing toxic H2S.
