Novel monocyclic macrocyclic compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
具有氮桥头原子的新型单环大环化合物,在碳氢桥链中至少有两个额外的
硫、氧或氮等杂原子,当与兼容的阳离子给体化合物混合时,形成稳定的含阳离子的大环化合物,这些大环化合物可以通过添加酸或季
铵化剂方便地解离。这些新型大环化合物可用于与
螯合剂相同的方式和目的。
