Öğe Crystal Structure of Dichloridobis[5-nitro-1-trimethylsilylmethyl-1H-benzimidazole-?N3] cobalt (II) N,N-dimethylformamide solvate.(Int Union Crystallography, 2010) Yalcin, Serife Pinar; Akkurt, Mehmet; Sireci, Nihat; Kucukbay, Hasan; Tahir, M. Nawaz[Abstract Not Available]Öğe Dichloridobis[5-nitro-1-trimethylsilylmethyl-1H-benzimidazole-?N3]cobalt(II) N,N-dimethylformamide solvate(Int Union Crystallography, 2010) Akkurt, Mehmet; Yalcin, Serife Pinar; Sireci, Nihat; Kucukbay, Hasan; Tahir, M. NawazThe title compound, [CoCl2(C11H15N3O2Si)(2)]center dot C3H7NO, was synthesized from 5-nitro-1-trimethylsilylmethyl-1H-benzimidazole and cobalt(II) chloride in dimethylformamide. The Co-II atom is coordinated in a distorted tetrahedral environment by two Cl atoms and two N atoms. In the crystal structure, there are a number of C-H center dot center dot center dot Cl and C-H center dot center dot center dot O hydrogen-bonding interactions between symmetry-related molecules.Öğe Preparation and characterization of trimethylsilyl-substituted benzimidazole metal complexes and structural characterization of dichlorobis[1-(trimethylsilyl)methyl-1H-benzimidazole-N3]cobalt(II)(Taylor & Francis Ltd, 2010) Sireci, Nihat; Kucukbay, Hasan; Akkurt, Mehmet; Yalcin, Serife Pinar; Tahir, M. Nawaz; Ott, HolgerThe ligands 1-trimethylsilylmethylbenzimidazole, 5-methyl-1-trimethylsilylmethylbenzimidazole, and 5-nitro-1-trimethylsilylmethylbenzimidazole and their Co(II) and Zn(II) complexes were synthesized and characterized by 1H-NMR, 13C-NMR, and elemental analyses. The crystal structure of dichlorobis[1-(trimethylsilyl)methyl-1H-benzimidazole-N3]cobalt(II) has been determined by single crystal X-ray diffraction.Öğe Synthesis, characterization and microwave-assisted catalytic activity of novel benzimidazole salts bearing piperidine and morpholine moieties in Heck cross-coupling reactions(Wiley-Blackwell, 2011) Kucukbay, Hasan; Sireci, Nihat; Yilmaz, Ulku; Akkurt, Mehmet; Yalcin, Serife Pinar; Tahir, M. Nawaz; Ott, HolgerA mixture of novel benzimidazole salts (2a-f), Pd(OAc)(2) and K(2)CO(3) in DMF-H(2)O catalyzes, in high yield, the Heck cross-coupling reaction assisted by microwave irradiation in a short time. All synthesized novel benzimidazole derivatives were characterized by elemental analysis and NMR spectroscopy. In addition, the molecular structure of 2a was determined by X-ray crystallography.

NawazA mixture of benzimidazole salts (2-7), Pd(OAc)(2) and K2CO3 in DMF-H2O catalyzes the Suzuki-Miyaura cross-coupling reactions promoted by microwave irradiation resulting in high yield within a short time. In particular, the yield of the Suzuki-Miyaura reactions with aryl bromides was found to be nearly quantitative. The synthesized benzimidazole salts (2-7) were identified by H-1-C-13, NMR, IR spectroscopic methods and microanalysis. The molecular structure of 1 was determined by X-ray crystallography. The antibacterial and antifungal activities of the novel benzimidazole derivatives (1-7) were also tested against standard strains. Copyright (C) 2011 John Wiley & Sons, Ltd.
