Chemical Properties
white to slightly blue or light grey cryst. powder
Uses
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.
Purification Methods
Dissolve it in MeCN, add dry Et2O until cloudy and cool at -20o in a freezer. The light blue precipitate is collected and dried in a vacuum oven at 130o/20mm for 8hours. It has 737nm ( 22.4 max M1cm -1) in AcOH. [Salomon & Kochi J Am Chem Soc 95 330 1973]. It has also been dried in a vessel at 0.1Torr by heating with a Fischer burner [Andrist et al. J Org Chem 43 3422 1978]. It has been dried at 110-120o/5mm for 1hour before use and forms a *benzene complex which should be handled in a dry box because it is air sensitive [Kobayashi et al. Chem Pharm Bull Jpn 28 262 1980, Salomon & Kochi J Am Chem Soc 95 330 1973]. [Beilstein 3 IV 34.]
