Novel macrocyclic (monocyclic and bicyclic) 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.
该文献描述的是新型大环化合物,包括单环和双环化合物,具有氮桥头原子,并且在烃桥链中至少含有两个额外的杂原子,包括硫、氧和氮。当与相容的阳离子供体化合物混合时,形成稳定的阳离子含有的大环化合物复合物,这些复合物可以通过加入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。
