Brief description, advantages, further prospects for application.
The interaction of bis-eteruphenylglycoluril with benzoaza-15-crown-5 derivatives in polyphosphate acid was studied, and bis(benzoazacrown-ethers) with fragments of diphenylglycoluril were obtained for the first time. The use of benzoaza-15-crown-5 with an unsubstituted nitrogen atom gives a low yield of the target product. The introduction of substituents on the Nitrogen atom makes it possible to increase the yield up to 40-42%. It has been shown by spectrophotometric titration that bis(benzoazacrownether) with a methyl group on the Nitrogen atom forms only 1:1 complexes with alkali and alkaline earth metal cations. The conclusion is made about the formation of intramolecular sandwich complexes with potassium cations and rubidium. The results obtained significantly expand the knowledge about the structure and properties of macroheterocyclic compounds and, in their significance, correspond to the world level.
