General description

Dysprosium(III) trifluoromethanesulfonate (Dysprosium(III) triflate) is a lanthanide triflate.

Application

Dysprosium(III) trifluoromethanesulfonate, a water-tolerant Lewis acid, has been used in the following studies:
  • Aldol reaction of silyl enol ethers with aldehydes.
  • As an effective catalyst for electrophilic substitution reactions of indoles with imines.
  • As catalyst for the synthesis of 4-aminocyclopentenones and functionalized azaspirocycles, via intramolecular aza-Piancatelli rearrangement.
  • As new curing initiator to study the curing of diglycidyl ether of bisphenol-A (DGEBA).
Catalyst for:
  • Aza-Piancatelli rearrangement
  • Friedel-Crafts alkylation
  • Ring-opening polymerization reactions
  • Microwave-assisted Kabachnik-Fields condensation
  • Cycloaddition reactions (Lewis-acid catalyst)
  • Fries rearrangement
  • Enantioselective glyoxalate-ene reactions
