Tetra-μ-acetato-κ8O:O′-bis{[2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole-κN3]copper(II)}
Qiang Wang,Cai-Feng Bi,Da-Qi Wang,Yu-Hua Fan
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809025276
Abstract: The title complex, [Cu2(CH3COO)4(C16H12N2O2)2], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two CuII atoms [Cu...Cu = 2.7254 (11) ] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be described as tetragonal-pyramidal derived from the calculation of the value τ = 0.0018. The apical positions of the tetragonal-pyramidal copper coordination polyhedra are occupied by the N atoms of 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands. In the crystal structure, molecules are linked into a chain by intermolecular C—H...O hydrogen bonds parallel to [010]. Two furan rings are disordered over two positions in ratios of 0.55:0.45 and 0.69:0.31.

Abstract: In the title complex, [CdI2(C16H12N2O2)2], the CdII atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands and two I atoms in a distorted tetrahedral configuration. The benzimidazole rings in adjacent molecules are parallel, with an average interplanar distance of 3.486 . The I atom is disordered over two sites in a 0.85 (5):0.15 (5) ratio.

Abstract: In the title complex, [CdCl2(C16H12N2O2)2], the CdII ion exhibits site symmetry 2. It shows a distorted tetrahedral coordination defined by two N atoms from symmetry-related 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands and by two symmetry-related Cl atoms. Intramolecular C—H...O hydrogen bonds stabilize the molecular configuration. Adjacent molecules are linked through C—H...Cl hydrogen bonds into a network structure.

Abstract: In the molecule of the title compound, C20H16Cl2N2O2, the planar benzimidazole ring system is oriented with respect to the furan and dichlorobenzene rings at dihedral angles of 53.39 (6) and 31.04 (5)°, respectively. In the crystal structure, intermolecular C—H...Cl hydrogen bonds link the molecules into centrosymmetric R22(8) dimers. These dimers are connected via a C—H...π contact between the benzimidazole and the furan rings, and π–π contacts between the benzimidazole and dichlorobenzene ring systems [centroid–centroid distances = 3.505 (1), 3.567 (1), 3.505 (1) and 3.567 (1) ].

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811012232
Abstract: In the title complex, [Cu(ClO4)2(C7H12N2O)2], the Cu(II) ion lies on a crystallographic inversion centre. The coordination sphere around Cu(II) ion can be described as tetragonally distorted octahedral with two perchlorate O atoms occupying the apical positions and four N atoms from two N1-(2-furylmethyl)ethane-1,2-diamine ligands in the basal plane.
Antifungal Activity of Resveratrol against Botrytis cinerea Is Improved Using 2-Furyl Derivatives  [PDF]

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0025421
Abstract: The antifungal effect of three furyl compounds closely related to resveratrol, (E)-3,4,5-trimethoxy-β-(2-furyl)-styrene (1), (E)-4-methoxy-β-(2-furyl)-styrene (2) and (E)-3,5-dimethoxy-β-(2-furyl)-styrene (3) against Botrytis cinerea was analyzed. The inhibitory effect, at 100 μg ml?1 of compounds 1, 2, 3 and resveratrol on conidia germination, was determined to be about 70%, while at the same concentration pterostilbene (a dimethoxyl derivative of resveratrol) produced complete inhibition. The title compounds were more fungitoxic towards in vitro mycelial growth than resveratrol and pterostilbene. Compound 3 was the most active and a potential explanation of this feature is given using density functional theory (DFT) calculations on the demethoxylation/demethylation process. Compound 3 was further evaluated for its effects on laccase production, oxygen consumption and membrane integrity of B. cinerea. An increase of the laccase activity was observed in the presence of compound 3 and, using Sytox Green nucleic acid stain, it was demonstrated that this compound altered B. cinerea membrane. Finally, compound 3 partially affected conidia respiration.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808004510
Abstract: The asymmetric unit of the title compound, C20H16N2O, contains two molecules. The dihedral angles between the benzimidazole ring systems and the attached benzene rings are 10.6 (5) and 13.7 (5)°. The conformers are linked by bifurcated three-centre hydrogen bonds, forming chains along the diagonal of the ab plane. The packing is further stabilized by π–π and C—H...π interactions.

Abstract: the polymerization of poly (2- furyl) methylenesulfide ? polythiofurfural ? was performed in an 0.36 mol/l aqueous solution of furfuraldehyde, saturated by bubbling hydrogen sulfide for 2 h at different temperatures. the reaction product was thoroughly washed and dried at 40 °c under vacuum. poly (2-furyl) methylenesulfyde is a yellow powder with a rather unpleasant odor. the polythiofurfural obtained [ -ch(c4h3o)-s-] is a furan with thiols end groups. these are active adsorption centers for metal ions. the polythiofurfural was soluble in acetone and chloroform and its yields attained 80%. morphological analysis by scanning eletronic microscopy indicates a regular and dense surface in an interesting spacial arrangement. preliminary isotherms adsorption studies indicate specific affinity forni (ii) and co (ii) and different capacity adsorption, 0.022 and 0.045 mmol per gram, respectively.

Ming-Liang Liu
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812017357
Abstract: The asymmetric unit of the title compound, C8H5F3N2, consists of two half-molecules, one lies on a mirror plane and the other is generated by twofold rotation symmetry, with the axis running through the trifluoromethyl C atom and the attached benzimidazole C atom. The two 2-trifluoromethyl-1H-benzimidazole molecules are connected by N—H...N hydrogen bonds involving the disordered NH H atoms into chains running parallel to the c axis. One of the trifluoromethyl groups is disordered over two orientations of equal occupancy.
