Abstract Cyclic and acyclic ligands containing the hydroxypyridinone (HOPO) moiety as donor group are known as strong coordinating compounds for a wide variety of metal ions. Based on the diaza-crown[18]ether Kryptofix K22, five different tendentate ligands were prepared using 1,2-HOPO, 1,2,3-HOPO and 2,3-Me-HOPO as additional binding moieties. The diaza-crown ether basic skeleton was furnished with
摘要 含有羟基吡啶酮(HOPO)部分作为供体基团的环状和无环配体被认为是多种金属离子的强配位化合物。基于二氮杂冠[18]醚 Kryptofix K22,使用 1,2-HOPO、1,2,3-HOPO 和 2,3-Me-HOPO 作为附加结合部分制备了五种不同的齿状配体。二氮杂冠醚基本骨架具有两个伯胺官能团,随后与相应的HOPO酸或HOPO酰氯反应,在最终脱保护后通过两个合成步骤获得所需的HOPO衍生物。所有化合物均通过 NMR 和 MS 分析得到证实。
