The complexations of N,N-dicarboxymethyl macrocyclic ether-bislactones and amine-bislactam, N-tosyl-macrocyclic ether-bislactones, and 4'-(dansylamin)benzo-18-crown-6 with Li+, Na+, K+, Cs+, Cd2+ and Pb2+ ions were studied by 1H, 7Li, 23Na, 133Cs NMR and the formation constants of complexes were calculated by nonlinear-least-squares program KINFIT. Also a 133Cs NMR technique was developed for the measurement of formation constants of crown ether complexes that uses competition of a crown ether and I- for a given Cs+.
Key words: LACTONES, NMR SPECTROMETRY, NITROGEN HETEROCYCLICS, CROWN ETHER COMPOUNDS, PROTON MAGNETIC RESONANCE SPECTROMETRY, LITHIUM ISOTOPES, CYCLIC ETHER, LEAST SQUARE METHODS, COMPLEX CONSTANT, SODIUM ISOTOPES
