New investigation of 1-substituted imidazole derivatives as thermal latent catalysts for epoxy-phenolic resins

Novel 1-substituted imidazole derivatives (4-10) were synthesized by imidazole and the corresponding substituted reagents (chloromethylpivalate, diphenylphosphinicchloride, di-tert-butyldicarbonate, 1,1′-oxalylchloride, pyrazine, phneylisocyanat, and p-toluensulfonylchloride). Polymerization of diglycidyl ether of bisphenol A (DGEBA) with 1-substituted imidazole derivatives, two commercial available catalysts (imidazole and 1-cyanoethyl-2-ethyl-4-methylimidazole) and N-benzylpyrazinium hexafluoroantimonate were investigated as model reactions of epoxy resin systems with respect to the thermal latency and storage stability of the catalysts. The catalytic activity of I-substituted imidazole derivatives 4-10 depended on the steric and withdrawing electronic effect of the substitution groups. To characterize the cure activation energy and the viscosity-storage time, the order of thermally latent activity is 1-tosylimidazole (6) > 1,1′-oxalyldiimidazole (8) > N-benzylpyrazinium hexafluoroantimonate (BPH, 3) > 1-tritylimidazole (9) > N-phenyl-imidazole-1-carboxamide (5) > 3-(diphenylphosphinoyl)imidazole (7) > tert-butyl-1H-imidazole-1-carboxylate (4) > 1-cyanoethyl-2-ethyl-4-methylimidazole (2E4MZ, 2) > 1-[(pivalyloxy)methyl]imidazol (10) > imidazole (1). In comparison with commercially available catalysts imidazole (1) and 1-cyanoethyl-2-ethyl-4-methylimidazole (2) and a cationic latent catalyst N-benzylpyrazinium hexafluoroantimonate (BPH, 3) as the standard compounds, in addition to 1-[(pivalyloxy)methyl]imidazole (10), the I-substituted imidazole derivatives (4-9) revealed better thermal latency.

Copper corrosion inhibitors in near neutral media

The efficiency of nontoxic imidazole derivatives as copper corrosion inhibitors in sodium chloride solutions was studied by electrochemical polarization methods (Tafel extrapolation and polarization resistance method) and weight-loss measurements. Results obtained during this study show that inhibitors with higher molecular weight, especially those with a phenyl ring, have better inhibiting properties. The values of free energy of adsorption, as calculated from Freundlich isotherm, indicate that investigated imidazole derivatives physisorbe on the copper surface. (C) 2002 Elsevier Science Ltd.

Antioxidant potential and antimicrobial screening of some novel imidazole derivatives: greenway efficient one pot synthesis

A series of substituted imidazoles have been synthesized under solvent-free condition by grinding 1,2-diketone, aromatic aldehyde, and ammonium acetate in the presence of molecular iodine as the catalyst. The short reaction time and easy workup make this protocol practically and economically attractive and are characterized by NMR spectra, X-ray, mass, and CHN analysis. Their antioxidant potential were evaluated using different in vitro antioxidant models namely, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical, superoxide anion, and hydroxyl radical scavenging activities. Their antibacterial screening against Staphylococcus aureus, Escherichia coli, and Klbesiella pneumoniae and antifungal activity against Aspergillus niger, Aspergillus flavus, and Candida-6 were also evaluated. Among all, dimethoxyphenyl substituent at N3 of the imidazole derivatives exhibited the highest hydroxy and superoxide anion radical scavenging activities, whereas dimethoxyphenyl substituent at N3 and fluorophenyl at C2 of the imidazole derivatives exhibited the highest DPPH radical scavenging activity.

Photoinduced Intramolecular Electron Transfer and Electronic Coupling Interactions in pi- Expanded Imidazole Derivatives

An intramolecular excited charge transfer (CT) analysis of imidazole derivatives has been made. The determined electronic transition dipole moments has been used to estimate the electronic coupling interactions between the excited charge transfer singlet state ((CT)-C-1) and the ground state (S-0) or the locally excited state ((LE)-L-1). The properties of excited (CT)-C-1 state imidazole derivatives have been exploited by the significant contribution of the electronic coupling interactions. The excited state intramolecular proton transfer (ESIPT) analysis has also been discussed.

Complexes of zinc phthalocyanine with monoaxially coordinated irnidazole-derivative ligands

Three complexes of zinc phthalocyanine (ZnPc) monoaxially ligated by imidazole, N-methylimidazole and N-(2-pyrimidinyl)imidazole were obtained in crystalline forms. Complexes containing imidazole and N-methylimidazole crystallise in the centrosymmetric space group of the triclinic system, while with the N-(2-pyrimidinyl)-imidazole complex crystallises in P2(1)/n space group of monoclinic system. Interaction of the electropositive polarised Zn centre of a planar ZnPc with nucleophilic ring nitrogen atom of imidazole derivatives leads to deviation of Zn form the N-4-plane of phthalocyaninato(2-) macrocycle by similar to 0.45 angstrom. Steric hindrance of the axial ligands of ZnPc-L complexes modify the pi center dot center dot center dot pi interactions between the Pc(2-) macrocycles when compared to that of the parent ZnPc pigment. The calculated threedimensional MESP maps are helpful for understanding of the interaction between the ZnPc and imidazole derivatives forming the monoaxially ligated complexes. Theoretical calculations of axial bonds energies and UV-Vis spectroscopic measurements in solutions also were performed. (C) 2016 Elsevier Ltd. All rights reserved.

Tuning the Adsorption Interactions of Imidazole Derivatives with Specific Metal Cations

In this work, we report a computational study of the interactions between metal cations and imidazole derivatives in the gas phase. We first performed a systematic assessment of various density functionals and basis sets for predicting the binding energies between metal cations and the imidazoles. We find that the M11L functional in combination with the 6-311++G(d,p) basis set provides the best compromise between accuracy and computational cost with our metal…imidazole complexes. We then evaluated the binding of a series of metal cations, including Li+, Na+, K+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Ba2+, Hg2+, and Pb2+, with several substituted imidazole derivatives. We find that electron-donating groups increase the metal-binding energy, whereas electron-with-drawing groups decrease the metal-binding energy. Furthermore, the binding energy trends can be rationalized by the hardness of the metal cations and imidazole derivatives, providing a quick way to estimate the metal…imidazole binding strength. This insight can enable efficient screening protocols for identifying effective imidazole-based solvents and membranes for metal adsorption and provide a framework for understanding metal…imidazole interactions in biological systems.
