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.
具有氮桥头的全新大环(单环和双环)化合物,在其烃基桥链中至少含有两个额外的杂原子,这些杂原子选自包括硫、氧和氮的组中,当与相容的阳离子供体化合物混合时,会形成稳定的含阳离子大环复合物,这些复合物反过来可以通过加入酸或季铵化剂方便地分离。这些新颖的大环化合物在用作螯合剂方面具有相同的价值和应用目的。
