Novel benzo-15-crown-5 and 18-crown-6 derivatives bearing an ionizable hydrazone group were synthesized and complex formation equilibria of the compounds with alkali metal ions in solvent extraction were evaluated spectrophotometrically. Formation of 2:2 complexes of the crown ethers with metal ions was observed using chloroform as an extraction solvent. |
