| Özet |
| Five novel 3-alkyl-4-cinnamoylamino-4, 5-dihydro-1H-1, 2, 4-triazol-5-ones (2) were synthesized by the reactions of 3-alkyl-4-amino-4, 5-dihydro-1H-1, 2, 4-triazol-5-ones (1) with cinnamoyl chloride and characterized by elemental analyses and IR, 1H NMR, 13C NMR and UV spectral data. The newly synthesized compounds 2 were titrated potentiometrically with tetrabutylammonium hydroxide in four non-aqueous solvents such as isopropyl alcohol, t-butyl alcohol, acetonitrile and N, N-dimethylformamide and the half-neutralization potential values and the corresponding pKa values were determined for all cases. In addition, these new compounds (except compound 2a) and five recently reported 3-alkyl-4-isobutyrylamino-4, 5-dihydro-1H-1, 2, 4-triazol-5-ones (3) were screened for their antioxidant activities. |
