The reaction of oximes with benzyl bromide catalyzed by benzyldimethyltetradecylammonium chloride was carried out at room temperature for 30～60 min in aqueous sodium hydroxide solution under ultrasound irradiation to give O-benzyloxime derivatives in 60%～96% yields. In comparison to classical methods, the advantages of present procedure include short reaction time, high yields and environmental friendliness.

Key words: phase transfer catalysis, oxime ether, ultrasound, etherification
