COPPER(II) TRIFLUOROMETHANESULFONATE Usage And Synthesis
Reaction
  1. Ring-Opening of epoxides and aziridines.
  2. Asymmetric conjugate addition of organozinc reagents to α,β-unsaturated ketones.
  3. Electrophilic addition of olefins.
  4. Asymmetric aziridination of olefins.
  5. Asymmetric cycloadditions and aldol condensations.
  6. Asymmetric Kharasch oxidation.
  7. Asymmetric Michael addition of enamides.
  8. Asymmetric O-H or O-R insertion reactions.
  9. Enantioselective intramolecular aminooxygenation of alkenes.
  10. Enantioselective addition of dialkylzinc reagents to N-acylpyridinium salts.
  11. Pd-catalyzed C-H functionalizations of oximes with arylboronic acids.
  12. Used as a Lewis acid in the Nazarov cyclization.
  13. Catalyst in the diacetoxylation olefins.
  14. Catalyst in the meta-selective direct arylation of α-aryl carbonyl compounds.
  15. Catalyst in the three-component coupling of amines, aldehydes, and alkynes.


Chemical Propertieswhite to slightly blue or light grey cryst. powder
Purification MethodsDissolve 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.]
