설명
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.
