A series of substituted phenoxyacetoxyalkylphosphonates bearing fluorine were designed and synthesized. All the new compounds were identified by elemental analysis, IR, 1H NMR and MS and were tested for herbicidal activity in greenhouse at a rate of 1.5 kg/ha. The results of preliminary bioassay showed that fluorine moiety introduced to the core structure could help to improve the herbicidal activity
设计并合成了一系列带有氟的取代苯氧基乙酰氧基烷基膦酸酯。通过元素分析,IR,1 H NMR和MS鉴定了所有新化合物,并以1.5 kg / ha的速率测试了温室中的除草活性。初步生物测定的结果表明,引入核心结构的氟部分可以帮助提高除草活性,苯环中带有3-三氟甲基的化合物表现出更高的抑制活性。
