Synthesis and Characterization of Methoxy-Substituted Salamo-Type Bisoximes Based on Bis(aminooxy)alkane and 3-Methoxy-2-hydroxybenzaldehyde

摘要

Four new methoxy-substituted Salamo-type bisoxime compounds 6,6'-dirnethoxy-2,2'-[(propylene-1,3-diyldioxy)bis(nitrilo-methylidyne)]diphenol (H2L~1), 6,6'-dimethoxy-2,2'-[(butylene-1,4-diyldioxy)bis(nitrilomethylidyne)Jdiphenol (H2L~2), 6,6'-dimethoxy-2,2'-[(propane-1,5-diyldioxy)bis(nitrilome-thylidyne)]diphenol (H2L~3) and 6,6'-dimethoxy-2,2'-[(hexane-1,6-diyIdioxy)bis(nitriIo-methylidyne)]diphenol (H2L~4) have been synthesized through condensation reactions under hot ethanol medium, respectively and characterized by elemental analyses, IR, UV-visible and ~1H NMR spectra.
