Synthesis and Characterization of ortho-Xylyl Linked Bis -benzimidazolium Salts (Part-II)

摘要

A number of N-alkylbenzimidazoles were synthesized by reactions of benzimidazole with alkyl halides (PentBr, HexBr, OctBr, DecBr). The subsequent treatment of the resulting N-alkylbenzimidazoles with l,2-bis(bromomethylene) benzene afforded corresponding bis-benzimidazolium salts. All the compounds were characterized by spectroscopic techniques (NMR and FT-IR) and microanalysis. Molecular structures of selected compounds were established through single crystal X-ray diffraction studies.
