Synthesis and spectroscopic characterization of new Schiff bases containing the benzo-15-crown-5 moiety

Molecules. 2004 Sep 30;9(10):860-6. doi: 10.3390/91000860.


New crown ether Schiff base derivatives were prepared by the condensation of 4'-formylbenzo-15-crown-5 or 4'-formyl-5'-hydroxybenzo-15-crown-5 with 1,2-bis(2-aminophenoxy)ethane. The structures of these new compounds were confirmed on the basis of elemental analysis, IR, (1)H- and (13)C-NMR, UV-Vis and mass spectroscopic data.
