Specifications

Description

Applications
Trimethylsilyl trifluoromethanesulfonate is used to prepare powerful Lewis acid, difluoroboron triflate etherate in acetonitrile solvent. It is also used as a reagent in a Dieckmann-like cyclization of ester-imides and diesters. Further, it is used in the conversion of carbonyl compounds to their enol ethers. It is also employed for chemical glycosylation reactions. Its reactivity is similar to trimethylsilyl chloride and is also involved in organic synthesis.

Solubility
Miscible with aliphatic, aromatic hydrocarbons, haloalkanes and ethers. Immiscible with water.

Notes
Moisture and air sensitive. Store in a cool place. Incompatible with strong oxidizing agents and strong bases.
