The Syntheses and Characterization of Three Novel Macrocyclic Polyether Ligands and Some of Their Alkaline Metal Complexes

Abstract

<em>The macrocyclic ligands 2,3,5,6-Bis{3'-bromo-5'-tert-butyl benzo-5-phenyl benzo} 12C3 (L₁), 2,3,5,6-bis{3'-bromo-5'-tert butyl-benzo-5'-phenyl-benzo}15C4 (L₂), 2,3,5,6-bis{3'-bromo-5'-tert butyl-benzo-5'-phenyl-benzo}18C5 (L₃) have been synthesized and their alkaline metal compounds with NaClO₄∙H₂O and KClO₄ have been prepared. Chemical formulas of all compounds have been characterized by using elemental analyses and spectroscopic techniques.</em>
