一般描述
3-Cyano-4-methylcoumarin is a 3-substituted 4-methylcoumarin derivative. Its structural properties, vibrational frequencies and electronic spectra has been studied by density functional theory (DFT). It has been reported to be formed during the Knoevenagel condensation of o-hydroxyacetophenone with ethyl cyanoacetate catalyzed by calcined Mg-Al hydrotalcite. Synthesis of 3-cyano-4-methylcoumarin, via condensation of o-hydroxyacetophenone with ethyl cyanoacetate in the presence of sodium ethylate, has been reported.

The vibrational and electronic spectra of 3-cyano-4-methylcoumarin (3C4MC) are reported and discussed. In this work the structural properties, vibrational frequencies and electronic spectra of 3C4MC have been investigated extensively using density functional theory (DFT) employing B3LYP exchange correlation with the
