In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27 (4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation. The mol-ecules are linked into a three-dimensional framework with a parallel laminated constru...

We report herein the synthesis of substituted 2-[4-(1,2-dimethyl-5-nitro-1H-imidazol-4-yl)phenyl]-1-arylethanols, ethyl 3-[4-(1,2-dimethyl-5-nitro-1H-imidazol-4-yl)-phenyl]-2-hydroxypropanoate and 2-[4-(1,2-dimethyl-5-nitro-1H-imidazol-4-yl)benzyl]-2-hydroxy-acenaphthylen-1(2H)-one from the reactions of 4-[4-(chloromethyl)phenyl]-1,2-dimethyl-5-nitro-1H-imidazole with various aromatic carbonyl ...

A new series of 2-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole derivatives containing a 1,2,4-triazole ring were synthesized via microwave technique. This efficient procedure provides pure products within a few minutes. The newly synthesized compounds were confirmed by (1) H NMR and (13) C NMR spectra and they were screened for their lipase inhibition and antioxidant activities. Compounds 4...

Thermodynamic data for the proton and metal ion complexation equilibria of imidazole ( 1,3 diazole, glyoxaline ) and histamine ( 4-imidoazolethylamine, 4 ( 2’ aminoethyl ) imidazole ) have been collected and critically evaluated. The literature search has been performed by using IUPAC’s “Stability Constants Database” and covers the literature until 1992. Important criteria for acceptance compri...
