Abstract
A series of quaternary ammonium salts has been tested as phase transfer agents to promote condensation reactions in an aqueous solution of sodium hydroxide in the absence of any organic solvent. Methyltrioctylammonium chloride (Aliquat® 336) emerges as the most efficient catalyst. Sonication of the reaction media has a poor but positive kinetic effect.
