Description

General description

Chlorotriethylsilane may be used as a silylating reagent for the preparation of trisilyl ethers from alcohols in the presence of a base such as imidazole, pyridine or 4-(dimethylamino)pyridine. It is found to be more reactive when used with pyridine as a solvent.

Application

Chlorotriethylsilane may be used as a derivatizing reagent for the determination of fluoride, in toothpaste samples using headspace solid-phase microextraction and gas chromatography–flame ionization detection.

Other Notes

Silylating agent with some advantage over the trimethylsilylating agents for synthetic and analytical applications
