摘  要:
[Aims] In order to find high activity and low toxic 2-(4-aryloxyphenoxy)propionic acid ester herbicides.[Methods] Two novel 2-(4-aryloxyphenoxy) propionic acid ester derivatives(5 a,5 b) were synthesized from the intermediate 2-(4-aryloxyphenoxy)propionic acid acyl and benzo [1,3] dioxol-5-yl-methanol,based on the structure of haloxy-p-methyl.Their structures were confirmed by ~1H NMR,HRMS and optical rotation.The herbicidal activities were tested.[Results] The preliminary bioassay results showed that the title compound 5 a has good herbicidal activities on monocotyledon species of Alopecurus aequalis and Polypogon fugax,and the inhibition rate reached to 90% at the dosage of 150 g a.i./ha.[Conclusions] The title compound has the herbicidal activity,which provides basis for further research and development of 2-(4-aryloxyphenoxy)propionic acid ester herbicides.
