haloalkyl, R
4
is selected from halo, and R
5
is selected from H or halo. Compared with the compounds in the prior art, the compound of General Formula I of the present invention has a higher activity at a low concentration. This reduces the amount of the compound used and the residue of the compound in farmland, and is thus environmentally friendly.
本发明公开了一种具有杀虫活性的一般式I的吡唑酰胺化合物,以及用于制备一般式I化合物的一般式II的中间体,其中R1选自氯或CN,R2选自H、C1-C3烷基、C1-C3卤代烷基或C1-C5烷氧基烷基,R3选自卤或C1-C3卤代烷基,R4选自卤,R5选自H或卤。与先前技术中的化合物相比,本发明的一般式I化合物在低浓度下具有更高的活性。这降低了化合物的使用量和在农田中的残留量,因此对环境更友好。
