Lithium selective ionophores based on pendant arm substituted crown ethers

Ligands have been synthesised which offer good selectivity for lithium ions over sodium based on substituted 14-crown-4 derivatives which bear diamide groups on the ethylene chain or, less effectively, on the central carbon of the propylene chain.The behaviour of potentiometric membrane electrodes based on these ionophores is compared.

Synthesis of Benzo-13-crown-4 Derivatives

A series of nine, new benzo-13-crown-4 compounds which bear one or two substituents on the three-carbon bridge has been prepared in good yields by cesium fluoride-assisted cyclization reactions of catechol with ditosylates of the appropriate glycols.The solid state structure of 9,9-dibenzyl-2,3-benzo-13-crown-4 is determined and compared with the reported structure for the unsubstituted crown ether.
