Abstract
Diethyl 2-(4-methylbenzylidene)malonate was synthesized by Knoevenagel condensation reaction of 4-methylbenzaldehyde and diethyl malonate in the presence of catalytic amount of piperidine and trifluoroacetic acid in benzene under reflux conditions. The product obtained was characterized by 1H NMR, Mass spectroscopy and by X-ray diffraction studies. The title compound C15H18O4 crystallizes in the monoclinic crystal system with space group C2/c and unit cell parameters, a = 18.210(4) Å, b = 8.316(2) Å, c = 20.130(4) Å, β = 109.0(2)° and Z = 8. The crystal and molecular structure of the title compound is stabilized by CH ···O hydrogen bond interactions.
