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 m
alonate. We determined the optimum conditions of the
reaction by studying the effect of solvent and catalyst nature and reaction
conditions on the condensation.
