摘要
在KF/Al2O3催化下,邻硝基芳香醛与氰乙酸酯或丙二腈发生羰基与活性亚甲基的缩合反应,得到高收率的缩合产物,且为E式异构体。
The carbonylactivated methylene condensation reaction of aromatic aldehydes with cyanoacetate or malononitrile has been carried out smoothly in the presence of potassium fluoride on alumina with high yield,and only the E isomers were obtained as the products
