Comparative Study of Mono- and Di-substituted 14-Crown-4 Derivatives as Lithium Ionophores

Kataky, Ritu,Nicholson, Patrick E. Patrick,Parker, David

, p. 321 - 327 (2007/10/02)

14-Crown-4 derivatives bearing either one or two methoxy, methoxycarbonylmethyl or carbamoylalkyl substituents have been prepared in an attempt to obtain selective ionophores for lithium ions.Complexation with lithium has been fabricated and evaluated using the fixed interference method.The highest selectivity for lithium with respect to sodium is observed for a diamide derivative (630:1).
