New pyrrolo[1,2-a]benzimidazoles were easily obtained in good yields via 1,3-dipolar cycloaddition reactions of benzimidazolium ylides with non-symmetrical electrondeficient alkynes in the presence of an oxidant such as tetrapyridinecobalt(II)dichromate using different acid acceptors to generate benzimidazolium ylides from the corresponding 3-phenacyl-benzimidazolium bromides. New synthesized pyrrolo[1,2-a]benzimidazoles were fully characterized by multinuclear NMR spectroscopy and X-Ray crystallography. (Chemical Equation Presented). |
