Using cyenopyrafen as the lead compound, a series of novel pyrazole acrylonitrile compounds were designed and synthesized via the reaction of butylphenylacetonitrile with the corresponding (substituted pyrazol‐5‐yl) methanone of pyrethroid alcohols in the presence of potassium tert‐butoxide. These compounds showed prominent acaricidal activity against Tetranchus urticae. In particular, IIf, IIh, IIo
在叔丁醇钾存在下,通过丁基苯基乙腈与拟除虫菊酯醇的相应(取代的吡唑-5-基)甲酮反应,以氰基吡喃苯甲醛为主要化合物,设计和合成了一系列新型的吡唑丙烯腈化合物。这些化合物表现出明显的对毛螨的杀螨活性。特别地,I如果,IIH,IIO,和IIP显示极好的活性,其中所述中值致死浓度均低于0.4毫克/升。此外,还讨论了目标化合物的构效关系。
