N,N′‐Dicyclohexylcarbodiimid eignet sich als Kondensationsmittel zur Darstellungvon Estern des Dantrons (1) mit Carbonsäuren. Es werden bessere Ausbeuten erzielt als bei der Reaktion von Dantron mit Säurechloriden. Mit Propion‐, Capron‐, Caprin‐ und Stearinsäure entstanden bei der Carbodiimidmethode fast nur die Monoester.
N, N' - 二环己基碳化二亚胺适合作为缩合剂用于制备 dantron (1) 与羧酸的酯。与 Dantron 与酰氯的反应相比,可获得更高的产率。对于丙酸、己酸、癸酸和硬脂酸,在碳二亚胺法中几乎只形成单酯。
