Knoevenagel Condensation Catalyzed by Potassium Fluoride/Alumina
Abstract:
The Knoevenagel condensation of aromatic aldehydes with ethyl cyanoacetate or cyanoacetamide has been carried out smoothly in the presence of potassium fluoride on alumi-na in high yield of products,and only the E isomers of the products were obtained.
