“…However, a similar approach has been used very rarely for the study of metal cation -sugar interactions: for example, the binding of Na' to D-ribose and to cis-inositol in water was observed through the variation of the 2 3~a spin-lattice relaxation rates in the presence of sugar (17). In pyridine, the large dissymmetry of the electronic distribution around the sugarcomplexed sodium cation permitted to define precisely the complexation parameters (18,19).…”

ZHIGANG CHEN, NICOLE MOREL-DESROSERS, JEAN-PIERRE MOREL; and CHRISTIAN DETELLIER Can. J. Chem. 72, 1753Chem. 72, (1994. The interactions of the La(II1) cation with D-ribose and with D-arabinose in aqueous solution were investigated by 1 3 9~a NMR spectroscopy. In the case of D-ribose, the formation of a La(II1)-sugar complex was indicated by variations of the ' 3 9~a chemical shift and linewidth with an increase of the sugar concentration in solution. In contrast, the complexation of La(II1) by arabinose is very weak and almost undetectable by "' La NMR. On the basis of a 1:l stoichiometry, the stability constant for the complex of La (II1)

Die Entwicklung der Fourier-Transform-Tehnik hat die 23Na-NMR-Spektroskopie zu einem wichtigen Hillsmittel werden lassen, mit dem der Organiker wie der Bio-Anorganiker Phanomene der Solvatation und der Ionenpaar-Bildung direkt beobachten kann. Die chemische Verschiebung und die Linienbreite von 23Na-Signalen erschliekn Komplexstabilitatskonstanten, Korrelationszeiten von Reorientierungsvorgangen und die Mikrodynamik in der Koordinationssphare des Natrium-Ions. In Konkurrenzexperimenten konnen mit der 23Na-NMR-Spektroskopie auch die Bindungsverhaltnisse weiterer Kationen studiert werden.

Complex Formation between Sugars and the Sodium Cation in Non‐Aqueous Solvents

Abstract: SummaryIn low dielectric solvents such as pyridine or isopropylamine, sodium perchlorate interacts strongly with a variety of sugars. The interaction is best described as nonspecific, with close proximity of the ionic partners maintained, as in a sugar-shared ion pair.
