摘要：

Application of ultrasound has been found to greatly assist the Knoevenagel aldol condensation reaction of activated methylenes with aromatic aldehydes under mild conditions. The outcome of the ultrasound-promoted reaction depends upon the electronic nature of the aromatic aldehyde, the solvent employed and the addition of acids, bases or ammonium salts.
