Öğe 1,3-Bis(3-phenylpropyl)-1H-benzimidazole-2(3H)-tellurone(Blackwell Publishing, 2008) Yalcin, Serife Pinar; Akkurt, Mehmet; Yilmaz, Uelkue; Kucukbay, Hasan; Buyukgungor, OrhanThe title compound, C25H26N2Te, was synthesized from bis[1,3-bis(3-phenylpropyl)benzimidazolidin-2-ylidene] and Te in a toluene solution. The molecule possesses a twofold rotation axis passing through the Te atom and the center of the benzimidazole ring system. The benzimidazole ring system makes an angle of 67.9 (4) with the phenyl rings.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.
