The influence of the substitution pattern on the herbicidal properties is discussed, and conclusions on the active site of the biphenol structure are drawn. It was observed that type and position of the halogen substituents have a significant influence on the activity of the core structure. The hydroxy functionalities play a crucial role for the effectiveness of the tested compounds. Because the blocking
测试了多种卤代2,2'-联苯酚作为作物保护剂的适用性。在施用后通过喷雾稀释溶液观察到这些化合物对四种典型害虫植物的活性。尽管它们的结构相当简单,但发现所研究的化合物显示出令人惊讶的高除草效果。为了更好地了解结构与活性之间的关系,对分子的特定位点进行了化学修饰,从而逐渐改变了核心结构。讨论了取代模式对除草性能的影响,并得出了有关双酚结构活性位点的结论。观察到卤素取代基的类型和位置对核心结构的活性具有显着影响。羟基官能度对于测试化合物的有效性起着至关重要的作用。因为羟基部分的封闭导致性能急剧下降,所以这些官能团在芳环上的存在似乎是必不可少的。
