A new method is described for the preparation of 2-perfluoroalkylether- benzimidazoles through the N-monoacyl derivatives of o-phenylenediamine. 2-pentafluorophenylbenzimidazole has been obtained by the reaction of o-phenylenediamine and pentafluorobenzoic acid in the presence of polyphosphoric acid. 2-Perfluoroalkylbenzimidazoles have been prepared in excellent yields by direct condensation of o-phenylenediamine
