| 摘 要： | 在Nd-SnCl2-H2O体系中, 用烯丙基溴超声诱发下进行了一系列芳香醛的烯丙基反应, 室温反应50～60 min得76%～93%烯丙基化产物; 而不用超声波时同样体系中搅拌3～4 h高烯丙基醇产率为30%～86%. 该方法时间短、产率高、环境友好.

| Abstract: | The allylation reactions of aldehydes with allyl bromide were carried out in 76%-93% yields with Nd-SnCl2-H2O under ultrasound irradiation at room temperature for 50-60 min. The reactions in the same system gave homoallylic alcohols in 30%-86% yields without ultrasound irradiation under stirring for 3-4 h. The main advantages of the present procedure are shorter reaction time, higher yield and environmentally benign way. |
