Beschreibung

Anwendung

Catalyzes direct substitution of allylic, propargylic, and benzylic alcohols with sulfonamides, carbamates, and carboxamides.

Bismuth(III) trifluoromethanesulfonate may be used as a catalyst in the following processes:

• deprotection of acetals
• cleavage of 2-tert-butoxy derivatives of thiophenes and furans
• allylation of acetals to form homoallyl ethers

It may also be used as a substitute to corrosive triflic acid in Friedel-Crafts (FC) acylation and sulfonylation of arenes.

Verpackung

Bismuth(III) trifluoromethanesulfonate is an eco-friendly Lewis acid that can be prepared by reacting triflic acid with bismuth(III) trifluoroacetate.
