A broad range of benzophenone hydrazone derivatives was prepared and tested against selected chewing insect pests, allowing the analysis of structure-activity relationships. Good activity was found only when the aromatic rings were substituted at the 4-positions with an halogen atom and a triflate or perhaloalkoxy group. In contrast, a number of substituents on the hydrazone part led to active compounds
制备了广泛的二苯甲酮衍生物,并针对选定的咀嚼害虫进行了测试,从而分析了结构-活性关系。仅当芳环在4-位被卤素原子和三氟甲磺酸酯或全卤代烷氧基取代时,才发现良好的活性。相反,部分上的许多取代基导致活性化合物,用酰基型取代基可获得最佳结果。在针对斜纹夜蛾的半田间试验中证实了最佳代表的出色的实验室和温室活性。
