A convenient, simple and green process for the synthesis of 2,4,5-triaryl-1H-imidazole and 1,2,4,5-tetraaryl-1H-imidazole derivatives using snail shell, which is abundant in Morocco, as a catalyst in ethanol at 40 °C has been developed. Additionally, short reaction times, excellent yields, simple procedure and relative non-toxicity of the catalyst are other noteworthy advantages and make this m...

Low-temperature studies of the simple variously substituted imidazole types 4-phenyl-1H-imidazole, C9H8N2, 1-benzyl-1Himidazole, C10H10N2, and 1-mesityl-1H-imidazole, C12H14N2, extend comparisons between parent imidazole species and their derivatives, the pronounced double-bond localization opposite the substituted N atom common to simple neutral species being redistributed aromatically on prot...
The inability to meet the desired outcomes of anticancer treatment and decrease in success bacterial fungal infections accelerated research these areas. Our group has conducted numerous studies, especially on benzimidazole ring systems’ antiproliferative antimicrobial activities. In this study, activity compounds was tested against A549, A498, HeLa, A375, HepG2 cancer cell lines by MTT assay. A...
Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...

Name: 1,3-Dihydro-1-methyl-2H-imidazole-2-thione IUPAC Systematic Names: 1-Methylimidazole-2-thiol; 1-methyl-4-imidazoline-2thione Synonyms: 2-Mercapto-1-methyl-1H-imidazole; 2-mercapto-1-methylimidazole; mercazolylum; 1-methyl-1,3-dihydroimidazole-2-thione; N-methylimidazolethiol; 1-methyl-2-imidazole...
This study aimed to use an existing ligand (imidazole)-assisted 1H-nuclear magnetic resonance (1H-NMR) spectroscopy protocol determine sulfate content of seaweed sulfated saccharides. Twenty samples – spanning nine species and multiple geographic locations were analyzed. Extracts obtained by immersing freeze-dried seaweeds in boiling water, followed alginate precipitation. Remaining supernatant...
The title compound, C(15)H(9)BrN(2)S, was prepared by the reaction of 1-bromo-2-(2,2-dibromo-vin-yl)benzene with 1H-benzo[d]imidazole-2(3H)-thione. The thia-zolo[3,2-a]benz-imidazole fused-ring system is nearly planar, the maximum atomic deviation being 0.049 (4) Å. This mean plane is oriented at a dihedral angle of 71.55 (17)° with respect ot the bromo-phenyl ring. π-π stacking is observed in ...
