Convenient and effective procedures for the synthesis of benzo-12-crown-4, benzo-15-crown-5, benzo-18-crown-6, benzo-21-crown-7 and benzo-24-crown-8 under phase-transfer catalysis conditions have been developed.
Multiple Benzo-fused Crown Ethers - Synthesis, Ion Selectivities in Membrane Electrodes and Inclusion of Water

New oligo-benzo-condensed crown-6 ligands 4, 6 - 9 having a different gradation of lipophilicity and of molecular rigidity are synthesized.For the known ligands 3 and 5 of similar constitution improved methods of preparation are described.The carrier efficiencies and ion selectivities of the various ligands for alkali and alkaline earth metal ions in liquid membrane electrodes of different composition are determined and discussed on the basis of the potentiometric selectivity factors lgKPotMgM.The possible behaviour of the new macrocycles in molecular inclusion is studied.A stable crystal lattice inclusion compound of 4 with water of composition 4*1/2 H2O is obtained.
