Abstract
Novel lariat ethers with pendent N-alkyl- and N-arylsulfonyl carbamoyl groups are synthesized in two steps from sym-(decyl)dibenzo-16-crown- 5-oxyacetic acid; for competitive solvent extraction of alkali metal c ations from aqueous solutions into chloroform by these proton-ionizabl e lariat ethers with 'tunable' acidity, the selectivity order is Na+ m uch greater than K+ with no detectable extraction of Li+, Rb+ or Cs+.
