Preparation and Characterization of new Knoevenagel condensation products of isophthalaldehyde and terephthalaldehyde with some active methylene compounds


Abstract in English

six new products using Knoevenagel condensation of isophthalaldehyde and terephthalaldehyde have been prepared with the following active methylene compounds: malononitrile, methyl cyano acetate, ethyl cyano acetate, dimethyl malonate and diethyl malonate. We determined the optimum conditions of the reaction by studying the effect of solvent and catalyst nature and reaction conditions on the condensation.
