Description

General description

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

Application

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

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).
