Linking salicylaldimine units with a 2,9-diazadecane strap in high yields via a simple Mannich condensation generates a ligand which forms 2 â¶ 2 â¶ 1 assemblies of Cu â¶ L â¶ anion in which the anion is encapsulated in a tetra-cation cavity.
通过简单的曼尼希缩合反应,将水杨醛亚胺单元与 2,9- 二氮杂癸烷表带高产连接起来,生成了一种配体,这种配体可形成 2 - 2 - 1 的 Cu - L - 阴离子组合体,其中阴离子被包裹在一个四阳离子空腔中。

The pH-dependence of simultaneous metal- and sulfate- loading of simple salen derivatives demonstrates the feasibility of their application as extractants for recovery of base metals from the leaching of sulfidic ores. The efficacy of the ligands depends on the templating of the sulfate binding site by the attendant metal ion.
