“…Chemical shifts of NH peaks of compounds 4 and 5 could not be detected. Reason of this probably is the tautomeric equilibrium of the hydrogen atom in the imidazole ring between the two nitrogen atoms [30,31]. This fl uxional behaviour causes acidic character of NH proton.…”

Abstract. 5,6-Dichloro/dimethyl-2-(2´,3´/2´,4´/2´,5´/3´,4´/3´,5´-dimethoxyphenyl)-1H-benzimidazoles were synthesized and characterized by using analytical data, FT-IR, FT-Raman, NMR, ESI-MS and fl uorescence spectroscopy. The optimized molecular geometry, zero point energy, dipole moment, ESE, band gap and charge distributions were calculated by Gaussian 09 using Density Functional Theory (DFT, RB3LYP) with 6-31++G(d,p) basis set. According to the calculations, the molecules have structures with various torsion angles between the benzimidazole and benzene rings from 9.7º to 47.8º. The calculated energy values with ZPE correction and DFT show that the methyl derivatives are more stable than the chloro forms. 3´,4´-Dimethoxy derivatives have higher decomposition points in comparison with the other compounds in series. The chlorine atoms of 5,6-dichloro-2-(2´,3´/2´,4´/2´,5´/3´,4´/3´,5´-dimethoxyphenyl)-1H-benzimidazoles are positively charged whereas the C5 and C6 carbon atoms are negatively charged due to the attached chlorine atoms, in virtue of the electron withdrawing characteristic of the imidazole part of the benzimidazole ring. Also, some calculated prominent bond lengths and bond angles were discussed.

“…Guadarrama et al studied the cytotoxic activity, X-ray crystal structures and spectroscopic characterization of cobalt(II), copper(II) and zinc(II) coordination compounds with 2-substituted benzimidazoles [27]. To the best of our knowledge, the study of the electrochemistry and electrocatalysis of zinc complexes containing benzimidazole are less reported [24][25][26][27]. The significance of this work is that it uses a new zinc complex [Zn(C 3 H 7 -bim) 2 Br 2 ] as a bulk-modifier, to fabricate a chemically modified carbon paste electrode monochromator.…”

“…Interest in exploring benzimidazole derivatives and their metal complexes has continually increased, since many of these materials may serve as models which mimic both the structure and reactivity of metal ion sites in complex biological systems [20][21][22][23][24][25][26][27]. Sandoval et al studied the synthesis, structure and biological activities of zinc(II) coordination compound with 2-benzimidazole derivatives [24].…”

Abstract:The present work reports the synthesis, characterization and performance of a new zinc(II) complex of [Zn(C 3 H 7 -bim) 2 Br 2 ] (bim = benzimidazole) as electrocatalyst for trichloroacetic acid and bromate reduction. Its structure was characterized by X-ray crystallography, IR spectroscopy and elemental analysis. The zinc atom adopts a distorted tetrahedral geometry by coordinating to two bromine atoms and two nitrogen atoms from two 1-propyl-1H-benzo[d]imidazole ligands. The electrochemical behavior and electrocatalysis of the zinc complex bulk-modified carbon paste electrode (Zn-CPE) have been studied by cyclic voltammetry. The Zn-CPE shows good electrocatalytic activities toward the reduction of trichloroacetic acid and bromate. The detection limit and the sensitivity are 0.05 μM, 67.43 μA μM -1 for trichloroacetic acid detection, and 0.02 μM, 69.94 μA μM -1 for bromate detection, respectively. This modified electrode shows good reproducibility, high stability, low detection limit, technical simplicity and possibility of rapid preparation, which is important for practical applications.
