| In the present study, nine novel 4-[(3-alkyl (aryl)-5-oxo-4, 5-dihydro-1H-1, 2, 4-triazol-4-yl)-iminomethyl]-phenyl 3-methoxybenzoates (3) were synthesized from the reactions of the corresponding 3-alkyl (aryl)-4-amino-4, 5-dihydro-1H-1, 2, 4-triazol-5-ones (1) with 4-formylphenyl 3-methoxybenzoate (2), which was obtained from the reaction of 4-hydroxybenzaldehyde with 3-methoxybenzoyl chloride by using triethylamine. The new compounds synthesized were characterized by using IR and 1H-NMR, 13C-NMR spectral data. The second part of the study, nine novel 4-[(3-alkyl (aryl)-5-oxo-4, 5-dihydro-1H-1, 2, 4-triazol-4-yl)-iminomethyl]-phenyl 3-methoxybenzoates (3) were titrated potentiometrically with TBAH in non-aqueous solvents (isopropyl alcohol, tert-butyl alcohol, acetone and N, N-dimethylformamide) and graphs were drawn for all cases. The half notralization potentials and pKa values were determined by half neutralization method [1]. In the third part of the study, the antioxidant properties of the compounds 3 were studied using by three antioxidant assays (reducing power, free radical scavenging and metal chelating activity). For the measurement of the reductive ability, Fe3+-Fe2+ transformation was investigated in the presence of title compound [2]. The hydrogen atoms or electrons donation ability of the synthesized compounds were measured by DPPH.[3]. The chelating effect of ferrous ions by the compounds were determined [4]. BHT, BHA and α-tocopherol were used as reference antioxidant compounds. |
