| Abstract: | Template condensation on the iron(II) ion matrix of three cyclohexanedione-1,2-dioxime molecules with esters of 1,4-pentadienylboronic acids afforded apically functionalized bis(diolefin)-containing clathrochelates, which are new potential monomers for the preparation of functionalized carbochain polymers. The complexes were characterized by the data of elemental analysis, UV-Vis spectroscopy, 1H, 11B, and 13C NMR spectroscopy, 57Fe Mössbauer spectroscopy, IR spectroscopy, and MALDI-TOF mass spectrometry. The molecular and crystal structures of the clathrochelates synthesized and the electron density distribution on a molecule of one of them were determined by X-ray diffraction analysis. |
