A series of bromo-substituted Salamo-type compounds have been synthesized by the reaction of 5-bromo-2-hydroxybenzaldehyde with 1,7-bis(aminooxy)heptane, 1,8-bis(aminooxy)octane, 1,9-bis(aminooxy)nonane or 1,10-bis(aminooxy)decane in hot ethanol medium, respectively, and characterized by elemental analyses, IR, UV-visible spectra and 1H NMR spectroscopy.
Four tetrahalogen substituted Salamo-type bisoximes H2L1-H2L4 have been synthesized from 3-bromo-5-chloro-2-hydroxybenzaldehyde and 1,7-bis(aminooxy)heptane, 1,8-bis(aminooxy)octane, 1,9-bis(aminooxy)nonane or 1,10-bis(aminooxy)decane in ethanol medium, respectively and characterized by elemental analyses as well as IR, UV-visible and 1H NMR spectroscopy. Salamo-type bisoxime compound is much more useful to assemble supramolecular systems than a Salen moiety.
