Description

Packaging

5 g in glass bottle

Application

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

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.

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.

Friedel–Crafts Acylation

The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form m...
