Description

Copper(II) trifluoromethanesulfonate acts as a catalyst in Diels-Alder reaction and cyclopropanation reactions. It is also used as a reagent for oligosaccharide synthesis. It acts as a Lewis acid. It is also employed in the dimerization of ketone enolates and tetramethylsilane enol ethers. It is used to prepare cis vinylic sulfones and oxazoles from alkynyl sulfones and ketones respectively. Further, it plays an important role for cyclization of dienolates. In addition to this, it is useful for dehydration of alcohols.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
