Studies on the insecticidal activities of some newN-benzoyl-N′-arylureas
摘要:
AbstractThis paper reports the synthesis and the insecticidal activities of some N‐benzoyl‐N'‐arylureas 4‐arylsubstituted with alkylated or halogenated aroyl moieties. The compounds, tested against some representative insect species, displayed very high activity against Aedes aegypti, especially the halosubstituted derivatives. None of the newly synthesized compounds showed genotoxic activity in the Bacillus subtilis rec‐assay and in the Salmonella‐microsome test.

4-Isopropyl-4'-nitro-benzophenon und Benzophenone der Formel 1
worin R Wasserstoff, eine Alkylgruppe mit 1 bis 20 C-Atomen, oder eine Alkoxygruppe mit 1 bis 20 C-Atomen bedeutet, wobei die Alkyl- oder Alkoxygruppe gegebenenfalls noch durch Sauerstoff unterbrochen sein kann, werden durch Umsetzung einer Verbindung der Formel II
mit einem p-Nitrobenzoylhalogenid in Gegenwart eines Friedel-Crafts-Katalysators in einem inerten Lösungsmittel hergestellt, wobei die Umsetzung bei Temperaturen von 10 bis 140°C in einem aliphatischen Kohlenwasserstoff, chlorierten aliphatischen oder chlorierten aromatischen Kohlenwasserstoff durchgeführt wird.
4-异丙基-4'-硝基二苯甲酮和式 1 中 R 为氢、1 至 20 个碳原子的烷基或 1 至 20 个碳原子的烷氧基(烷基或烷氧基有可能被氧打断)的二苯甲酮的制备方法是:在 Friedel-Crafts 催化剂存在下,将式 II 的化合物与对硝基苯甲酰卤在惰性溶剂中反应,反应温度为 10 至 140°C,在脂肪族烃类、氯化脂肪族烃类或氯化芳香族烃类中进行。
