Abstract
本发明涉及通式(I)的新型1-芳基-吡唑化合物,其中R1表示氢,烷基或卤代烷基,R2表示烷基,卤代烷基或每种情况下的任意取代的芳烷基或芳基,R3表示氢或卤素,Ar表示任意取代的苯基或吡啶基,n表示数字0,1或2,该化合物可用作抗害虫的制剂。
Description
本发明涉及新的1-芳基吡唑化合物,它们的制备方法以及作为杀灭害虫的药剂,更具体地是作为杀虫剂和杀蟎剂的应用。
现已知道,某些吡唑衍生物,例如象1-环己基-5-〔N,N-(二甲基)-氨基甲酰氧基〕-3-甲硫甲基-吡唑或1-环己基-5-〔N,N-(二甲基)-氨基甲酰氧基〕-3-甲磺酰-甲基-吡唑,具有杀虫的,杀线虫的和杀真菌的作用。
但是,这些化合物的作用水平和持续时间并不是在所有应用领域都总是令人完全满意的,尤其是对某些昆虫或在低浓度使用时是如此。
现已发现一种新的通式(Ⅰ)的1-芳基吡唑类化合物,
