Abstract

Heterocyclic compounds (5-9) were synthesized and reacted with 4,5-bis (bromomethyl) benzo-15-crown-5 to afford the fused benzocrown - heterocycle ligands (10-14). The complexing ability of these macrocyclic ligands toward Li+, Na+, K+, Mg2+, Ca2+, Li+/Mg2+ and Li+/K+ was measured by the solvent extraction method. The data show that extractability of the double cations enhances remarkably when compared with the extraction ability of the single cation.
