tert-Butyldimethylsilyl chloride Usage And Synthesis
IntroductionTriethylchlorosilane is a clear, colourless to yellowish, pungent smelling, caustic and flammable liquid. It can be dissolved in non-protonating solvents without decomposition.
It may be used as silylating agent for dervatization of primary and secondary alcohols etc.. Also it may be used to protect allylic esters as silylketene acetal which is ore stable but less volatile derivates than trimethylchlorosilane.
Chemical PropertiesWhite solid
UsesUsed to protect alcohols during organic synthesis.
DefinitionChEBI: A silyl chloride consisting of a central silicon atom covalently bound to one chloro, one tert-butyl and two methyl groups. tert-Butyldimethylsilyl chloride is a derivatisation agent used in gas chromatography/mass spectrometry ap lications.
HazardModerately toxic.
Purification MethodsFractionally distil it at atmospheric pressure. [Sommer & Tyler J Am Chem Soc 76 1030 1954, Corey & Venkateswarlu J Am Chem Soc 94 6190 1972, Beilstein 4 IV 4076.]
