Copper(I) trifluoromethanesulfonate benzene complex can be used as a catalyst:
- To synthesize enol-esters via copper(I) carboxylate intermediate formation.
- In the enantioselective allylic oxidation of cyclic alkenes.
- To prepare 2,5-disubstituted pyrrolidine derivatives from N-alkenyl, alkynyl and alkyl N-benzoyloxysulfonamides via the sulfonamidyl radical formation.
It can also be used in combination with amino acid-based chiral phosphine ligands to catalyze asymmetric conjugate additions of alkylzincs to acyclic α,β-unsaturated ketones, affording β-alkylcarbonyls in high yield and with excellent enantioselectivity.
