Various Aspects of Enantiomeric Recognition of (S,S)-dimethylpyridino-18-Crown-6by Several Organic Ammonium Salts

摘要

Factors responsible for complex stability and enantiomeric recognition for theinteractions of (S,S)-dimethylpyridino-18-crown-6 with several organic ammonium salts were examined using an H NMR technique. The results indicate that cation structures have a significant effect on enantiomeric recognition; solvents play a very important role in the stability of the complexes, and anions can compete with ligands for the ammonium cations.
