ligand. The five-position of the benzimidazole groups were substituted with tertiary butyl groups with the intention of preventing bis-ligation and oligomerization, as was observed in other studies using similar ligands. Unfortunately, even with the bulkier substituents, the new ligand still formed a bis-ligated structure. Although the new ligand did not afford the desired mono-ligated species under
摘要 在本文中,我们报道了双苯并咪唑羧酸酯配体的庞大变体。苯并咪唑基的五个位置被叔丁基取代,以防止双连接和低聚,这在使用类似配体的其他研究中也可以观察到。不幸的是,即使具有更大的取代基,新的配体仍形成双连接结构。尽管新配体在此处研究的条件下无法提供所需的单连接物种,但新配体和配位化合物的制备为正在进行的制备结构上忠实的2-组氨酸-1-羧酸酯模型配体提供了额外的设计原则。在仿生化学中。
