| Abstract: | The allylation reactions of aromatic aldehydes and ketones were carried out in 31–86% yield using SnCl2–H2O system under ultrasound irradiation at r.t. for 5 h. The reactions in the same system gave homoallyl alcohols in 21–84% yield with stirring at r.t. for 24 h. Compared with traditional stirring methods, ultrasonic irradiation is more convenient and efficient. |
