Abstract
Abstract A Schiff-base polyoxaazamacrocycle derived from 2, 5-diformylfuran and 1, 5-bis(2-aminophenoxy)-3-oxapentane was obtained by a template procedure as mononuclear lanthanide(III) and lead(II) complexes. In the absence of the metal salt the macrocycle was not formed. The complexes were characterized by elemental analysis, molar conductivity, mass spectrometry and IR, 1 H NMR and 13 C NMR spectroscopy. The reduction of the Pb II complex with sodium borohydride yielded a novel polyoxaazamacrocycle containing a furan head and aromatic lateral units; the X-ray crystal structure of its methanol inclusion compound is reported.
