Complexation of alkali cation picrates with cyclogentiotetraose peracetate (CGD4Ac) have been studied by 1H-N.M.R. spectroscopy in acetone d6 and nitromethane d3. We determined the stability constants directly from the observed change of the chemical shifts of H-4 and H-6 pro S protons of CGD4Ac at constant ligand concentration with increasing amounts of alkali salt. The stability constants have also been determined by multinuclear n.m.r. spectroscopies, from the observed change of the chemical… Expand
