Description

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

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.

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...
