A new phenanthroline derivative, 2-mesityl-1H-imidazo[4,5-f][1,10]phenanthroline (MEIP), was synthesized and characterized by elemental analysis, FT-IR, 1HNMR, 13CNMR spectra. MEIP evaluated as corrosion inhibitor for carbon steel in 0.5 M H2SO4 solution using gravimetric UV−visible spectrophotometric methods at 303−333 K. Results obtained show that is a good mild solution. The inhibition efficiency found to increase with concentration but decreased temperature, which suggestive of physical...
Eight imidazole-based compounds 4-methyl-2,6-bis(4,5-diphenyl-1H-imidazol-2-yl)phenol ( A-dp), 2-(1H-phenanthro[9,10-d]imidazol-2-yl)phenol B-2H), 5-methoxy-2-(1H-phenanthro[9,10-d]imidazol-2-yl)phenol B-2H4M), 3-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol C-3H), 2-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)-4-methoxyphenol C-2H5M), 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)-2-methoxyphenol C-4H3M), 2-(2-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline C-2M) and...
A series of 2-(imidazole-2-yl)phenol ligands L1−L6 with the general composition 4-R4-5-R3-6-R2-2-(4,5-R1,R1-1H-imidazole-2-yl)phenol (L1: R1 = C2H5, R2 R3 R4 H; L2: C6H5, L3: OCH3, L4: L5: H, CH3; L6: t-Bu) and L7 (2,4-di-tert-butyl-6-(1H-phenanthro[9,10-d]imidazol-2-yl)phenol) their neutral Zn(II) complexes (Z1−Z7) were synthesized characterized by spectroscopic elemental analyses. Molecular structures L1, L5, Z1, Z2 confirmed single-crystal X-ray diffraction. L1 crystallized in monoclinic...
Phenanthroline derivative, 2-(6-methylpyridin-2-yl)-1H-imidazo[4,5-f][1,10] phenanthroline (MIP) was synthesized and characterized by elemental analysis, FT-IR, 1H NMR, 13C single crystal X-ray diffraction study. MIP evaluated as corrosion inhibitor for mild steel in 0.5 M H2SO4 solution using gravimetric UV–Visible spectrophotometric methods at 303–333 K. Results obtained show that acts solution. The inhibition efficiency found to increase with concentration but decreased temperature....
The derivatization influence was studied for twelve 2,6-di(1<italic>H</italic>-imidazol-2-yl)phenols, whereby a strong fluorescent sensitivity Cr(<sc>iii</sc>) reported, while Zn(<sc>ii</sc>)/Cd(<sc>ii</sc>) sensing potentials also appeared.
Background: Current drugs available for the treatment of Chagas disease are fraught with several challenges including severe toxicity and limited efficacy. These factors coupled absence effective treating chronic stage have rendered development new against a priority. Keywords: Azoles, anti-parasitic agents, drug toxicity, trypanosomiasis, disease.
Importance of molecular access to Co(<sc>ii</sc>) site is shown by new tridentate disulfonamides, which stabilize uncommon 5-coordinate mixed-ligand vacant-octahedral geometries.
Corrosion behavior of mild steel immersed in 0.5 M H2SO4 and corrosion inhibition the presence different concentrations 2,4-di-tert-butyl-6-(1h-phenantro[9,10-d]imidazol-2-yl) phenol (PIP) was investigated using weight loss hydrogen evolution techniques at 303 – 333 K. The results indicate a maximum efficiency 68.45% 10 x 10-5 PIP inhibitory action acid solution is best described by Temkin adsorption isotherm. Arrhenius transition state equations are used to calculate activation parameters...
