Copper(II) trifluoromethanesulfonate, 99%
Description
Copper(II) trifluoromethanesulfonate is a mild lewis acid. It is used as catalyst which promotes dehydration of alcohols and diols to alkenes at ambient temperatures. It is widely used to generate carbenoid species from ?-diazo esters and ketones, via in situ reduction to the Cu(I) species. It is also promotes the reaction between diazo esters and imines to give aziridines. It catalyzes syn-selective aldol condensation of (Z)-silyl enol ethers with aldehydes, Friedel-Crafts alkylation, acylation reactions of aromatics and addition of trimethylsilyl cyanide to carbonyl compounds.
