Synthesis and Herbicidal Activities of New Aryloxyacetamide Compounds

Two series of new aryloxyacetamide compounds(Ⅰ,Ⅱ) were synthesized by using 4-chlorophenoxyacetic acid and substituted anthranilic acid as starting materials.Their chemical structures were confirmed by 1H NMR and MS spectra.The biological test results showed that,at the concentration of 100 mg/L,most of title compounds inhibited root and stem growth of target test plants,and the inhibitory rates of root were higher than that of stem.CompoundsⅠexhibited herbicidal activities more excellent than compoundsⅡ,and the compoundⅠ-2 have the strongest herbicidal activity.
