A series of N-substituted 5-chloro-6-phenylpyridazin-3(2H)-one derivatives were synthesized based on our previous work; all compounds were characterized by spectral data and tested for in vitro insecticidal activity against Plutella xylostella. The results showed that the synthesized pyridazin-3(2H)-one compounds possessed good insecticidal activities, especially the compounds 4b, 4d, and 4h which showed > 90% activity at 100 mg/L. The structure-activity relationships (SAR) for these compounds were also discussed.

哒嗪-3(2H)-酮衍
生物,通过光谱数据对所有化合物进行了表征,并测试了这些化合物对木虱的体外杀虫活性。结果表明,合成的
哒嗪-3(2H)-酮化合物具有良好的杀虫活性,尤其是化合物 4b、4d 和 4h,在 100 mg/L 的浓度下活性大于 90%。此外,还讨论了这些化合物的结构-活性关系(
SAR)。
