Abstract:

Hydroxycitronellal oxime(2) was synthesized from hydroxycitronellal(1) and hydroxylammonium chloride, and then reacted with bromoalkanes to give 4 hydroxycitronellal oxime alkyl ethers(3a-3d). The structures of the products were characterized by GC-MS, IR and NMR.The inhibitory effect of oxime and its alkyl ethers on the growth of annual ryegrass in different concentrations were determined by the plate method. The results showed that when the concentration of 3b was 0.31 mmol/L, the concentration of 3c was 0.63 mmol/L and the concentration of 3d was 2.50 mmol/L, the growth inhibition rate of the annual ryegrass roots were higher than that of diuronat the concentration of 10 mmol/L(94.1%). When the concentration of 3b and 3d were 0.31 mmol/L and the concentration of 3c was 0.63 mmol/L, the inhibitory rate on the growth of annual ryegrass stemswere higher than that of diuron at the concentration of 10 mmol/L(88.10%).
