Research methods - synthetic, IR, UV, NMR spectroscopy, mass spectrometry.The reaction of bistosylates or diiodides of 2,7-bis[2-(2-hydroxyethoxy)ethoxy]- or 2,7-bis{2-[2-(2-hydroxyethoxy)ethoxy]'ethoxy}fluorenone with tiluenesulfonamide in DMF or with benzyl amine in CH3CN under high dilution conditions at 80 ?C in the presense of potassium carbonate resulted in the formation of the first representatives of fluorenonoazacrownophanes and bis(fluorenono)diazacrownophanes as the products of [1+1] and [2+2] condensation in 12-58% yield. Similar condensation of bistosylates mentioned in DMF or diiodides in CH3CN with diaza-18-crown-6 afforded the corresponding fluorenonocryptand in the yields of 18 and 35%, respectively. It is set an extraction method, that azafluorenonophanes is capable effectively enough to connect both with cations of alkaline metals and ammonium. Product Description popup.authors Богащенко Т.Ю.
