  An especially robust compound and its derivative metal complexes that are approximately one hundred-fold superior in catalytic performance to the previously invented TAML analogs is provided having the formula: wherein Y1, Y2, Y3 and Y4 are oxidation resistant groups which are the same or different and which form 5- or 6-membered rings with a metal, M, when bound to D; at least one Y incorporates a group that is significantly more stable towards nucleophilic attack than the organic amides of TAML activators; D is a metal complexing donor atom, preferably N; each X is a position for addition of a labile Lewis acidic substituent such as (i) H, deuterium, (ii) Li, Na, K, alkali metals, (iii) alkaline earth metals, transition metals, rare earth metals, which may be bound to one or more than one D, (iv) or is unoccupied with the resulting negative charge being balanced by a nonbonded counteraction; at least one Y may contain a site that is labile to acid dissociation, providing a mechanism for shortening complex lifetime. The new complexes deliver catalytic performances that promise to revolutionize multiple oxidation technology spaces including water purification.

  一种特别强效的化合物及其衍生物金属配合物的催化性能比之前发明的 TAML 类似物高出约 100 倍，其分子式为 其中 Y1、Y2、Y3 和 Y4 是相同或不同的抗氧化基团，当与 D 结合时，它们与金属 M 形成 5 或 6 元环；至少一个 Y 含有一个基团，该基团对亲核攻击的稳定性明显高于 TAML 激活剂的有机酰胺；D 是金属络合供体原子，最好是 N；每个 X 都是添加易受路易斯酸性取代基的位置，如 (i) H、氘，(ii) Li、Na、K、碱金属，(iii) 碱土金属、过渡金属、稀土金属，这些取代基可与一个或多个 D 结合，(iv) 或未被占用，由此产生的负电荷由非键反作用平衡；至少一个 Y 可包含一个易受酸解离的位置，从而提供了一种缩短络合物寿命的机制。新复合物具有催化性能，有望彻底改变包括水净化在内的多个氧化技术领域。
