Özet
In this study, (E)-4,6-dibromo-2-[(3,5-dimethylphenylimino)methyl]-3- methoxyphenol and (E)-4,6-dibromo-2-[(2,6-dimethylphenylimino)methyl]-3- methoxyphenol compounds have been synthesized and characterized by using X-ray crystallographic method, FT-IR and Density functional method. The molecular geometry, vibrational frequencies of the title compounds in the ground state have been calculated by using B3LYP with the 6-31G(d,p) basis set. The tautomeric form of the compounds has been demonstrated by using single crystal X-ray method, FT-IR spectrometer and DFT method. In addition, HOMO-LUMO energy gap, molecular electrostatic potential map and NBO analysis of the compounds are performed at B3LYP/6-31G(d,p) level. It may be remarked that the free radical scavenging activities of the title compounds were assessed using DPPH, DMPD +, and ABTS+ assays. The obtained results show that especially compound 2 has effective DPPH (SC50 1.52 ± 0.14 μg/mL), DMPD+ (SC50 1.22 ± 0.21 μg/mL), and ABTS+ (SC50 3.32 ± 0.17 μg/mL) scavenging activities compared with standards (BHA, rutin, and trolox). © 2014 Elsevier B.V.
