Bis(trimethylsilyl)mercury a chemical reagent with formula: (CH3)3-Si-Hg-Si-(CH3)3.
Synthesis
This compound was first synthesized by Wiberg et al. in 1963, by the reaction of trimethylsilyl bromide with sodium amalgam:[1]
- 2 Na + Hg + TMSBr → TMS2Hg + 2 NaBr
Reactions
On prolonged heating at 100-160 °C, or when stood under light as an ethereal solution, it decomposes to hexamethyldisilane:[1]
- TMS2Hg → (CH3)3Si-Si(CH3)3 + Hg
Reaction with hydrogen chloride gives trimethylsilane and trimethylsilyl chloride:[1]
- TMS2Hg + HCl → TMSH + TMSCl + Hg
