series of novel diphenyl ether derivatives containing unsaturated carboxylates were designed and synthesized. Their structures were identified by 1H nuclear magnetic resonance and elemental analyses. The bioassays indicated that the compounds 5b and 5c exhibited good herbicidal activities against velvetleaf at a concentration of 30–40 g/hm2. The relationship between structure and herbicidal activity
设计并合成了一系列含有不饱和羧酸盐的新型二苯醚衍生物。通过1 H核磁共振和元素分析鉴定了它们的结构。生物测定结果表明,化合物5b和5c在30–40 g / hm 2的浓度下具有良好的除草作用。还讨论了结构与除草活性之间的关系。在不饱和羧酸酯基团中,丁烯酸酯是最有前途的一种。在它们上,由于具有高原卟啉原IX氧化酶抑制作用(pI ),4-乙氧基4-氧代丁烯基5-(2-氯-4-(三氟甲基)苯氧基)-2-硝基苯甲酸酯5b被确定为最有前途的候选物。50 = 6.64),并且对阔叶杂草具有良好的除草活性,对大豆具有选择性,对哺乳动物的毒性低。
