Abstract
The present invention discloses an N-alkyl-N-cyanoalkylbenzamide compound of General Formula I, an intermediate of General Formula II used to prepare the compound, wherein R1 is selected from halo or C1-C3 alkyl; R2 is selected from halo or CN; R3 is selected from halo, or C1-C3haloalkyl; R4 is selected from halo; R5 is selected from H or halo; R6 is selected from C1-C3alkyl, C1-C3 haloalkyl or C1-C5 alkoxyalkyl; R7 is selected from C1-C5 alkyl; and R8 is selected from hydrogen or C1-C5alkyl. Compared with the compounds in the prior art, the compound of General Formula I has a higher activity at a low concentration. Particularly, the compound of the present invention still has 60% or higher of the insecticidal activity at a concentration below 1 ppm. This greatly reduces the amount of the compound used and the residue of the compound in farmland, and is thus environmentally friendly.
