Successive treatment of cyanuric chloride with two aromatic diamines, at least one of them sulfonated, yields water-soluble sulfonated azacalix[4]arenes which may be isolated by crystallisation. Functionalised azacalixarenes may be made by first displacing two chloro substituents from the cyclisation precursor. Attempted formation of an azacalix[6]arene led to a dimeric species for which two structures may be proposed, one of them an azacalixarene catenane.
将
三聚氯氰与两个芳香族二胺(其中至少一个为磺化二胺)连续处理,可得到
水溶性磺化氮杂[4]烯,并可通过结晶分离出来。首先从环化前体中置换出两个
氯取代基,就可以制得官能化氮杂环
丙烯。在尝试形成氮杂[6]烯时,发现了一种二聚物,并提出了两种结构,其中一种是氮杂[6]烯猫烷。
