trimethylsilyl trifluoro methanesulfonate manufacturers in indiaTrimethylsilyl trifluoromethanesulfonate can be used to make powerful Lewis acid, difluoroborontriflate etherate, in an acetonitrile-based solvent. It can also be used in a Dieckmann-life cycle of ester-amides or diesters. It is also used to convert carbonyl compounds into their enol ethers. It can also be used in chemical glycosylation reactions. It is also used in organic synthesis because of its similar reactivity to trimethylsilyl chloride.


For the copper-catalyzed, asymmetrically allylic alkylation of allyl bromides and chlorides (AAA), trimethylsilyl trifluoromethanesulfonate was used in combination with boron trifluoride etherate.

It can be used as follows:

Used as a silylating agent in the synthesis trimethylsilyl-enol (ethers of a-diazoacetic acid)
To activate benzyl ethers and alkyl ethers for the alkylation sulfides.
To facilitate conversion of Diels Alder adducts from Danishefsky’s diene into cyclohexenones, without the formation methoxy ketone byproduct.
A powerful Lewis acid, especially in acetonitrile solvent, is required to prepare difluoroboron Triflate Estate.
Used as a reagent in a Dieckmann-like cycle of ester-amides or esters.

It can also be used as a catalyst:

Acylation of alcohols using acid anhydrides.
Reductive coupling carbonyl compounds and trialkyl silanes in order to create symmetrical ethers
Glycosidation 4-demethoxy daunomycin ones using 1- -acyl–L-daunosamine derivatives.
