NMR Study of Exchange Kinetics of the Lithium Ion With Cryptand C222 in Binary Acetonitrile-Nitromethane Mixtures

Ligand Exchange Processes on Solvated Lithium Cations: Complexation by Cryptands in Acetone as Solvent

“…This obser-vation corresponds to that reported by Shamsipur et al [35] for the exchange of Li + between C221 and acetonitrile/ nitromethane mixtures. In all solvent mixtures used, Li + exchange was found to occur through an associative mechanism, as expected for weakly donor solvents (DN = 14.1 and 2.7 for acetonitrile and nitromethane, respectively).…”

Host–Guest Complexes of Oligopyridine Cryptands: Prediction of Ion Selectivity by Quantum Chemical Calculations

“…[28,29] This is surprising since different cryptand/cryptate or crown ether-solvent combinations have been investigated, [30][31][32][33][34] especially with respect to their transport properties [35] or ion conductivity and potential applications in batteries and capacitors, [36] while parallel alkali and alkaline-earth ion complexes with phenanthroline and bipyridine moieties have also been studied. [37] In a recent report we demonstrated that ion selectivity can be studied by quantum chemical methods for [2.2.2] and smaller homologues.…”

Ligand‐Exchange Processes on Solvated Lithium Cations: Acetonitrile and Hydrogen Cyanide

“…[13][14][15][16][17][18] Use of its hydrogen derivative HCN is mostly prevented by its high toxicity and its boiling point of 25°C. Experimental studies dating back to the middle of the 20th century show that HCN is a water-like solvent that is well suited for dissolving organic and inorganic compounds.…”
