General description
Praseodymium (III) trifluoromethanesulfonate (Praseodymium(III) triflate) is a water-tolerant Lewis acid. It is an efficient catalyst employed for the synthesis of α-aminonitrile, via condensation of aldehydes, amines and trimethylsilyl cyanide.
Application
Praseodymium(III) trifluoromethanesulfonate (Praseodymium(III) triflate) was employed as catalyst for the aqueous aza-Diels-Alder reactions of aldehydes and dienes. It was also used as catalyst for the Aldol reaction of silyl enol ethers with aldehydes.
Catalyst for:
- Asymmetric α-amination reactions
- Polymerization reactions
- Regioselective reductive ring opening reactions
- Intermolecular hydroamination reactions
- Paal-Knorr condensation
- Friedel-Crafts alkenylation
- Friedel-Crafts acylation
- Biginelli reactions
