Synthesis and characterization of(E)-2-[(E)-benzylidene]heptanal oxime
The synthesis and characterization of(E)-2-[(E)-benzylidene]heptanal oxime(3)was reported.The target compound was synthesized by condensation reaction of α-amyl cinnamaldehyde(1)with hydroxylamm-onium chloride(2)under sodium hydroxide alkaline condition.It was found that the yield was 70.5％when the mole ratio of compound(2)to compound(1)was 1.4∶1 and the reaction was carried out in methanol at 50℃for 20min.The structure of the product was characterized by 1H NMR,13C NMR,ESI-MS and XRD single crystal diffraction.The synthesis method has the advantages of simple process,short reaction time and high yield.
