【摘要】 以α-对氯磺酰基苯氧基丙酸酯为原料,经氨化、甲酰化和胺解反应,合成了10个新型的取代芳脲磺酰基苯氧丙酸酯(4a~4 j),其结构经1H NMR,IR和元素分析确证。生测结果表明,4a~4 j均有一定的除草活性。更多还原

【Abstract】 Ten novel 2-[p-(arylurea-sulfonyl)phenoxy] propanates(4a~4j) were synthesized from 2-(p-chlorosulfonyl) phenoxy propanate by amination,formylation and aminolysis reaction.The structures were characterized by(~1H NMR,) IR and elemental analysis. Preliminary bioassay indicated that 4a~4j exhibited some herbicidal activities.更多还原
