Application

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.

Various enantiopure fluorous bis(oxazolines) with fluorine content between 52.7 and 58.7% have been synthesized by a simple reaction sequence that involved the introduction of two fluorinated ponytails by alkylation of the corresponding nonfluorous bis(oxazolines). These new ligands have been used
