Synthesis of 4,4'-bisaryl-2,2'-bisbenzimidazoles as building blocks for supramolecular structures.
A series of 4,4'-bisaryl-2,2'-bisbenzimidazoles has been synthesized from the corresponding 4,4'-dibromo-2,2'-bisbenzimidazoles by Negishi coupling reactions. This procedure affords highly substituted bisbenzimidazoles. [reaction: see text]
