Synthesis of 4,4‘-Bisaryl-2,2‘-bisbenzimidazoles as Building Blocks for Supramolecular Structures
摘要:
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.
