Synthesis and characterization of conjugated compounds containing two aldehyde groups
Using 2,5-dibromo-diethyl terephthalate and 4-acetylene benzaldehyde as raw materials,2,5-dibromo-diethyl terephthalate containing two aldehyde functional groups was successfully prepared by Sonogashira coupling reaction.The chemical structures of[4-(trimethylsilyl)acetylidene]benzaldehyde,4-acetylidene benzaldehyde and 2,5-bis[(4-formylphenyl)acetylidene]diethyl terephthalate were characterized by 1H-NMR.The conjugated compounds were successfully synthesized by hydrogen NMR spectroscopy.
