Conductance study of ion-pairing of dibenzo-24-crown-8 complexes with sodium monoalkyl benzeneazophosphonates in acetonitrile

Abstract Conductance study of ion-pairing of dibenzo-24-crown-8 complexes with a series of sodium monoalklyl benzeneazophosphonates in acetonitrile has been described. The values of the ion-pair dissociation constants, K D , and the limiting conductances, Λ O , of the complexes are reported. The results obtained are compared and discussed relative to the corresponding complexes of the 18-membered crown ether.
