Abstract

Sodium perchlorate complexes 2 of lipophilic macrotricyclic receptors 1 were obtained in high yield by following a synthetic route in which sodium cation acts as the templating agent in the last step. Complexes with several inorganic salts were directly prepared from the free ligands 1, obtained by decomplexation of 2, or via anionic exchange from the complexes 2. Extraction data of alkali halides under two-phase conditions (H20-CHC13) with ligand la ...
