Syntheses and Reactions of 2,2'-Bisbenzimidazole Systems

摘要

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.
