摘　　要：水介质中形成碳-碳键的优越性逐渐被人们所认知,近三十年来一直是研究的热点。研究了在室温和以低浓度酸或酸式盐溶液作为助催化剂的情况下,Mg、Al或Fe粉催化的苯甲醛的水相烯丙基化反应。研究结果表明:Mg、Al或Fe粉与0.1mol/L酸或酸式盐组成的催化体系都具有不同程度的催化活性,其中Fe粉和0.1mol/L磷酸溶液组成的催化体系的反应产率达到53.5%。The advantages of carbon-carbon bond formation in aqueous media are gradually being recognized by people,and have become the research hotspot over the recent three decades.In this paper,the allylation of benzaldehyde mediated by Mg,Al or Fe powder has been studied in the presence of a low-concentration acid or acid salt solution used as the catalyst promoter at room temperature.Research results showed that the catalytic systems,which were composed of Mg,Al or Fe powder with 0.1 mol/L acid or acid salt,demonstrated catalytic activity to different degree,and the product yield reached 53.5% in the presence of Fe powder in 0.1 mol/L phosphoric acid.
