Twenty-three crown ethers with a hydroxyl and an alkyl or aryl group linked directly to the central carbon of a three-carbon bridge were synthesized in one-step reactions of glycol and bisphenol dianions with substituted 2-(chloromethy1) oxiranes. Crown ether tertiary alcohols with methyl, n-decyl, n-tetradecyl, phenyl, and p-(ndecy1) phenyl substituents and four ring sizes are prepared. The effect of substituent on Na+ and K+ complexation is assessed by ...
