  2-Seleno-1-alkylbenzimidazoles and their diselenides: Synthesis and structural characterization of a 2-seleno-1-methylbenzimidazole complex of mercury

  摘要：

  2-Seleno-1-methylbenzimidazole, H(sebenzim(Me)), can be synthesized from 1-methylbenzimidazole by sequential treatment with (i) (BuLi)-Li-n, (ii) elemental selenium and (iii) HCl(aq). This method is also applicable to the synthesis of 2-seleno-1-t-butylbenzimidazole, H(sebenzim(But)). Single crystal X-ray diffraction and NMR spectroscopic data demonstrate that H(sebenzim(Me)) and H(sebenzim(But)) exist as the selone rather than the selenol tautomers, which is in accord with the results of density functional theory (B3LYP) calculations. The data also indicate that the selone is best represented as a C+-Se- zwitterion rather than as a C=Se doubly bonded species. Aerobic oxidation of H(sebenzim(Me)) and H(sebenzim(But)) in the presence of Et3N yields the diselenides, (sebenzim(Me))(2) and (sebenzim(But))(2). In addition, H(sebenzim(Me)) reacts with HgCl2 to give [H(sebenzim(Me))](2)HgCl2, the first structurally characterized example of a 2-seleno-1-alkylimidazole mercury complex. (C) 2012 Elsevier Ltd.
