The synthesis of fourteen mono-cationic and six dicationicanalogs of Hoechst33258 is described. The monocationic benzimiazoles 7a-7g and the dicationic benzimidazoles 9a-9c are obtained in five steps starting from 4-acetamidobenzonitrile. The monocationic bis-benzimiazoles 12a-12g are synthesized in four steps starting from 4-amino-3-nitrobenzonitrile. The dicationic bis-benzimiazoles 17a-17c are
