E. Luboch et al., SYNTHESIS AND ELECTRODE PROPERTIES OF 16-MEMBERED AZOCROWN AND AZOXYCROWN ETHERS - STRUCTURE OF TRIBENZO-16-AZOCROWN-6, Tetrahedron, 54(19), 1998, pp. 4977-4990
16-Membered benzoazo- and benzoazoxycrown ethers have been synthesized
by reductive macrocyclization of respective bis(nitrophenoxy)oxaalkan
es. The isomers of azocrown ethers were separated and E and Z structur
es were ascribed. Behavior of the compounds as ionophores in ion-selec
tive membrane electrodes has been studied. Structure of Z isomer of 16
-membered tribenzoazocrown ether has been determined. (C) 1998 Elsevie
