The condensations of benzyl cyanides with aromatic aldehydes under ultrasound irradiation have been studied in this paper.All the reactions occur with excellent yields and short time in the presence of potassium hydroxide as catalyst.The structure of product has been confirmed by IR,NMR,mass spec-trometry etc.The reaction could be worked up easily with short reaction time,high yields and environ-mental friendliness,which provides an effective new method for the synthesis of these compounds.
