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

Abstract

The macrocyclic ligands 2,3,5,6-Bis{3'-bromo-5'-tert-butyl benzo-5-pheny l benzo} 12C3 (L1), 2,3,5,6-bis{3 '-bromo-5'-tert butyl-benzo-5'-phenyl-benzo}15C4 (L 2), 2,3,5,6-bis{3 '- bromo-5'-tert butyl-benzo-5'-phenyl-benzo}18C5 (L 3) 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.
