摘要
在KF/Al_2O_3催化下,芳香醛与氰乙酸乙酯或氰乙酰胺发生羰基与亚甲基的缩合反应,得到高产率的缩合产物,且为E式结构。
The carbonyl - methylene condensation reaction of aromatic aldehydes with ethyl cyanoacetate or cyanoacetamide has been carried out smoothly in the presence of potassium fluorides on alumina in high yield of products,and only the E isomers of the products were obtained.
