Molecular Recognition as Shown by the Solvent Extraction of (R)- and (S) -Alpha-(1-Naphthyl)Ethyl Ammonium Picrate or Orange 2 by Chiral Pyridino-Crown Ethers
Abstract
A solvent extraction technique was used to determine equilibrium constants for the reaction of ALPHA-(L -NAPHTHYL)ETHYLammonium ions (R)- and (S) -isomers with chiral substituted pyridino- 18-crown-6 ligands in a water- chloroform system. Selectivity coefficients and stability constants for the interaction in chloroform solutions were calculated. The selectivity patterns are similar to those found by the 1H NMR technique. Thus, this method may be a simple and rapid way to determine enantiomeric recognition.
