Benzimidazole nitrogen-directed, regiocontrolled, lithiation of ferrocenyl- and phenyl-N-n-butylbenzimidazoles
2-Ferrocenyl- and 2-phenyl-N-n-butylbenzimidazoles were synthesized to evaluate the influence of the benzimidazole functional group upon their directed lithiation. The regiochemistry of lithiation was studied, as well as the effect of stabilization of the

Synthesis and structure of bifunctional N-alkylbenzimidazole phenylboronate derivatives
N-Methyl and N-n-butyl-2-(2-boronophenyl)benzimidazoles are accessed from the corresponding mono-N-alkyl-ortho-phenylenediamines, either using a polyphosphoric acid-mediated cyclisation with ortho-bromobenzoic acid, or preferably using an Oxone-mediated c
