Bis(trimethylsilyl)mercury a chemical reagent with formula: (CH3)3-Si-Hg-Si-(CH3)3.

Synthesis[edit]

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[edit]

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
