The present invention discloses a pyrazolamide compound of General Formula I having an insecticidal activity and an intermediate of General Formula II used to preparing the compound of General Formula I, wherein R1 is selected from chloro or CN, R2 is selected from H, C1-C3 alkyl, C1-C3 haloalkyl or C1-C5 alkoxyalkyl, R3 is selected from halo or C1-C3 haloalkyl, R4 is selected from halo, and R5 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通式I的吡唑酰胺化合物和一种用于制备通式I化合物的通式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选自卤代或C1-C3卤代烷基,R4选自卤代,R5选自H或卤代。与现有技术中的化合物相比,本发明通式 I 的化合物在低浓度下具有更高的活性。这就减少了化合物的用量,降低了化合物在农田中的残留量,从而有利于环保。
