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