    • Novel polycyclic macrocyclic compounds having four tertiary nitrogen bridgehead atoms and six bridging chains, each of which have not more than twelve directly connecting atoms between each pair of bridgehead nitrogens, said bridging chains being hydrocarbon chains and hetero-substituted hydrocarbon chains having at least one hetero connecting atom selected from the group consisting of oxygen, sulfur, and nitrogen, at least two of said chains being hetero substituted. When admixed with a compatible cation-donor compound, the polycyclic macrocyclic compounds form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing acid. The novel polycyclic macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.The polycyclic macrocyclic compounds are prepared by condensation reactions utilizing high dilution techniques, e.g. by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon di-carbonyl halide followed by reduction of the resulting lactam or, alternatively, by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon dihalide (or di-sulfonate).
    • 具有四个三氮桥头原子和六个桥连链的新型多环大环化合物,其每一个在每对桥头氮之间不超过十二个直接连接的原子,所述桥连链是烃链和具有至少一个杂原子的杂取代烃链 连接选自氧,硫和氮的原子,所述链中的至少两个是被取代的。 当与相容的阳离子供体化合物混合时,多环大环化合物形成稳定的含阳离子的大环络合物,其又可以通过加入酸或季铵化酸来方便地解离。 新型多环大环化合物以与螯合剂相同的方式和相同的目的使用是有价值的。
