| 摘 要： | 在Nd-CH3OH-HOAc(质量分数为36％)水溶液体系中,超声辐射下室温还原芳香醛,2h内可得到收率为48％～85％的邻二醇.而同样体系中搅拌24 h,邻二醇产率为36％～74％.该方法时间短,产率高,环境友好,没有单分子还原产物,化学选择性好.

| Abstract: | Reductive coupling reactions of aromatic aldehydes were carried out in 48%-85% yield of vicinal diol withNd-CH3OH-36% HOAc under ultrasound irradiation at r.t.for 2 h.The reactions in the same system gave vicinal diol in 36%-74% yield with stirring for 24 h.The main advantages of the present procedure are shorter reaction time,higher yield and harmonious environment.More important is,it has no single molecule reduction product,chemical selective. |
