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, Holger
The 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.
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, Holger
A 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.
