A one-pot method for the preparation of benzoyl metronidazole was achieved by using N,N'-carbonyldiimidazole as a coupling reagent. Moreover, it was found that the byproduct imidazole as the catalyst promoted the reaction. In addition, the β-cyclodextrin solubilization of benzoyl metronidazole was investigated by phase-solubility method. The phase-solubility studies indicated that the solubilit...

Solution equilibrium studies on Fe(III) complexes formed with imidazole-4-carbohydroxamic acid (Im-4-Cha), N-Me-imidazole-4-carbohydroxamic acid (N-Me-Im-4-Cha), imidazole-4-acetohydroxamic acid (Im-4-Aha), and histidinehydroxamic acid (Hisha) have been performed by using pH-potentiometry, UV-visible spectrophotometry, EPR, ESI-MS, and H1-NMR methods. All of the obtained results demonstrate tha...

The title compound, C(37)H(26)N(4)O(7), is a 1H-anthra[2,1-d]imidazole-2,6,11(3H)-trione derivative having isoindolindionylpropyl substitutents attached to the imidazole N atoms. The anthraquinone fragment is buckled, the dihedral angle between the two benzene rings being 1.6 (1)°. The two isoindoline rings of the substituents of the imidazole ring are positioned on opposite sides of the five-m...

The title compound, C16H14N4, is non-planar with dihedral angles between the planes of the imidazole and phenyl-enedi-amine rings of 30.66 (4)° and between the planes of the phenyl-enedi-amine and N-phenyl rings of 56.63 (7)°. In the crystal, mol-ecules are connected by N-H⋯N hydrogen bonds, generating a chain extending along the b-axis direction. The crystal structure is also stabilized by C-H...

Abstract The hydrophilicity of nanocellulose materials mitigates their good mechanical and oxygen barrier properties when exposed to humid conditions. It also limits use in many applications where water is present. This study reveals hydrophobic modification cellulose nanofiber (CNF) films with vinyl esters variable alkyl chain length using deep eutectic solvent (DES) imidazole triethylmethylam...

The asymmetric unit of the title compound, {[Co(3)Yb(2)(C(5)H(2)N(2)O(4))(6)(H(2)O)(4)]·2H(2)O}(n), contains one Yb(III) ion, two Co(II) ions (one situated on an inversion centre), three imidazole-4,5-dicarboxyl-ate ligands, two coordinated water mol-ecules and one uncoordinated water mol-ecule. The Yb(III) ion is seven-coordinated, in a monocapped trigonal prismatic coordination geometry, by s...

The structure of the title compound, C(9)H(6)I(2)N(2), contains two symmetry-independent mol-ecules. The inter-planar angles between the imidazole and phenyl ring planes are 16.35 (3) and 17.48 (6)°. Mol-ecules are connected via N-H⋯N hydrogen bonds to form zigzag chains along the b axis. The title compound is the first example of a structurally characterized 4,5-diiodo-imidazole with an organi...
