| Abstract: | The reactions of oximes with benzyl bromide catalyzed by benzyldimethyltetradecylammonium chloride are carried out at room temperature for 30–60 min in aqueous sodium hydroxide solution under ultrasound irradiation to offer O-benzyl oxime derivatives in 60–96% yields. In comparison to classical methods, the advantages of the present procedure include short reaction time, high yields and environmental friendliness. __________ Translated from Chinese Journal of Organic Chemistry, 2008, 28(4) (in Chinese) |
