摘要 文章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,研究了Sn粉催化的苯甲醛的水相烯丙基化反应。研究结果表明:Sn粉与0.1 mol.L-1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Sn粉与0.1 mol.L-1对甲苯磺酸溶液、0.1 mol.-L1酒石酸氢钠溶液组成的催化体系的反应产率分别高达82.1%和69.2%。 The allylation of benzaldehyde mediated by Sn powder in presence of lower concentration solution of acid or acid salt as catalyst promoter at room temperature was studied.The research results show that the catalysis systems,composed of Sn powder with 0.1 mol·L^-1 acid or acid salt,have catalytic activity to different extents,and the yield reaches 82.1% in presence of Sn powder in 0.1 mol·L^-1 p-Toluenesulfonic acid and 69.2% in presence of Sn powder in 0.1 mol·L^-1 sodium bitartrate.
