The invention describes novel l-aryl-5-(substituted alkylideneimino)pyrazoles of formula (I)
wherein typically preferred substituents are:
Rl is cyano, nitro, or halogen;
R² is R⁹S(O)n in which n is 0, l or 2 and R⁹ is alkyl, preferably methyl which is substituted by halogen atoms which are the same or different up to full substitution of the alkyl moiety;
R³ is hydrogen or alkyl;
R⁴ is phenyl or heteroaryl, optionally substituted by one or more hydroxy, halogen, alkoxy, alkylthio, cyano or alkyl or combinations thereof; preferably R⁴ is phenyl, which is at least substituted by 3-hydroxy or 4-hydroxy;
R⁵ is hydrogen, alkyl or halogen;
R⁶ and R⁸ are hydrogen;
R⁷ is halogen, alkyl, haloalkyl or haloalkoxy; and
X is a nitrogen atom or CRl4 in which Rl4 is hydrogen, halogen, cyano, alkyl, alkylthio or alkoxy.
The invention further describes processes to make the compounds, compositions of the compounds, and methods of use of the compounds for the control of arthropods (mites, aphids or insects), nematodes, helminths, or protozoa.
本发明描述了式 (I) 的新型 l-芳基-5-(取代亚烷基亚氨基)吡唑
其中通常优选的取代基是
Rl 是氰基、硝基或卤素;
R² 是 R⁹S(O)n,其中 n 是 0、l 或 2,R⁹ 是烷基,最好是甲基,甲基被相同或不同的卤素原子取代,直至烷基完全取代;
R³ 是氢或烷基;
R⁴ 是苯基或杂芳基,可选择被一个或多个羟基、卤素、烷氧基、烷硫基、氰基或烷基或其组合取代;R⁴ 最好是苯基,至少被 3-羟基或 4-羟基取代;
R⁵ 是氢、烷基或卤素;
R⁶ 和 R⁸ 是氢;
R⁷ 是卤素、烷基、卤代烷基或卤代烷氧基;以及
X 是氮原子或 CRl4,其中 Rl4 是氢、卤素、氰基、烷基、烷硫基或烷氧基。
本发明进一步描述了制造化合物的工艺、化合物的组合物以及使用化合物控制节肢动物(螨虫、蚜虫或昆虫)、线虫、蠕虫或原生动物的方法。
