In water, where it is not soluble, sodium salts of DSS, 2,2-dimethyl-2-silapentane-5-sulfonate, are used instead. Because of its high volatility, TMS can easily be evaporated ...

Witryna24 lut 2024 · Solvent choices for reactions involving organometallics of the alkali metals are critical. For example, n BuLi is decomposed by Et 2 O to give n BuH, C 2 H 4 and LiOEt. Alkali metal organometallics are extremely reactive and must be handled in air- and moisture-free environments; NaMe, for example, burns explosively in air.
