Аннотация:Novel ligands containing a 15- crown- 5 ether moiety and six- membered heterocyclic residues with different combinations of N atoms were prepared by condensation of methyl- substituted six- membered heterocyclic bases with 4'- formylbenzo- 15- crown- 5 ether; the best results were obtained in the presence of tBuOK in DMF. For dimethyl- substituted heterocyclic bases as the initial heterocyclic components, the competition of mono- and bis- condensation reactions is analyzed. The role of complex formation in the syntheses is discussed.
