【摘要】 为了开发新型的具有杀虫活性化合物，本研究设计并合成了一系列含氟嘧啶硫醚类化合物，结构经过¹H NMR和¹³C NMR进行表征，并采用浸叶法对其生物活性进行了测定。结果表明，目标化合物的产率为52%～88%，均对小菜蛾表现出一定的杀虫活性，其中化合物3m的活性最好，在质量浓度为1 mg/L时，对小菜蛾的致死率为97%。本试验为含氟嘧啶硫醚类杀虫剂的合成提供新的思路。更多还原

【Abstract】 In order to develop new compounds with insecticidal activity, a series of fluoropyrimidine thioethers compounds were designed and synthesized. The chemical structures of target compounds were characterized by ¹H NMR and ¹³C NMR and insecticidal activity was tested by leaf immersion method. The results showed that the yield of all of the new compounds were 52%-88%, and had certain control activity against Plutella xylostella, and when the mass concentration was 1 mg/L, the lethal rate of compound 3m to Plutella xylostella was 97%. The finding could provide a new idea for the synthesis of fluoropyrimidine thioethers compounds.更多还原
