Description

Application

Benzyltriethylammonium chloride is a lipophilic phase-transfer catalyst that can be used in phase-transfer catalysis (PTC) to catalyze polycondensation reactions to form high molecular weight polymers under bi-phasic conditions.

It can also be used:

• To activate hydroxyapatite and natural phosphate for use as a solid support for Knoevenagel condensation and Claisen-Schmidt condensation, respectively at room temperature and in the absence of a solvent.
• To increase the efficiency of mCPBA oxidation of sulfonimine generated from arenesulfonamide and diethyl acetal of an aromatic aldehyde to form 2-sulfonyloxaziridines.
• In combination with antimony(V) chloride to form a catalytic system for the Friedel-Crafts acylation reactions of arenes with acyl and sulfonyl chlorides.
