Abstract
Seven novel (benzy1oxy) methyl-substituted crown ethers with four ring oxygens and 13-, 14- , 15, and 16-membered polyether rings are synthesized and their lithium and sodium cation- binding abilities are assessed by solvent extraction of the aqueous alkali metal picrates. Strongest lithium ion complexation is observed with [(benzyloxy) methyl]-l4-crown-4 compounds.
