Nucleophilic reactions of two 2,2′-bisbenzimidazole systems, namely the bis(2H-benzimidazole-2-ylidene) 2 and the dispiro[2H-benzimidazole-2,1′-cyclohexane-4′,2″-2″H-benzimidazole] 3, as well as the syntheses of new 2,2′-bisbenzimidazoles are reported and their conversion into other heterocycles is described.
