The reaction of condensation of thiobarbituric acid (I) with 4-(N,N-dimethylamino) benzaldehyde(II) in ethanol in the presence of triethylamine (Et3N) was studied. The electronic structure of the reaction product of 5-[4-(N,N-dimethylamino) phenylmethylen]-2-thioxodihydropyrimidine-4,6-(1H,5H)-dione (III) was studied by the classical quantum chemical method ab initio HF/6-311G** in neutral, acidic and alkaline medium. The influence of the N,N-dimethylamino-group in benzaldehyde on its condensation with the methylene group of (I) was found. The influence of pH on the electronic structure of the condensation product (III) was studied. [ABSTRACT FROM AUTHOR] |
