Na+ Complexation of New Multidentate Polyether Ligands - Rapid Estimation of Complexation Constants by 23Na NMR Spectroscopy
Offermann, Werner,Weber, Edwin
, p. 234 - 245 (2007/10/02)
A new 23Na NMR method for fast and simple estimation of Na+ complex stabilities is reported and applied to various polyether ligands.Synthesis of the new coronands and podands amongst the employed substrates are given.
Effect of Chain Length and Heteroatom Position on Ammonium Ion Binding in Nitrogen-containing "Lariat" Ethers
Schultz, Rose Ann,Schlegel, Eric,Dishong, Dennis M.,Gokel, George W.
, p. 242 - 243 (2007/10/02)
Macrocyclic polyethers having polyethyleneoxy-sidechains extending from a nitrogen pivot bind ammonium ions quite strongly when an 18-membered ring and a two-oxygen sidechain are present; a 15-membered ring and other chain lengths give inferior binding.
LARIAT ETHERS. 3. MACROCYCLIC POLYETHERS BEARING DONOR GROUPS ON FLEXIBLE ARMS ATTACHED AT A NITROGEN PIVOT POINT
Schultz, Rose Ann,Dishong, Dennis M.,Gokel, George W.
, p. 2623 - 2626 (2007/10/02)
The binding of lariat ethers utilizing a nitrogen pivot atom for the donor sidearm is enhanced considerably relative to the carbon-based systems and this may be explicable in terms of diminished "sidedness."
