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,在烃桥链中至少有两个额外的杂原子(选择自
硫、
氧和
氮的群组中),当与兼容的阳离子供体化合物混合时,形成稳定的含阳离子的大环络合物,这些络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与
螯合剂的用途和目的相同。
