摘要

A pyrazolyl acrylonitrile compounds represented by the structures of Formula I: or stereoisomers thereof, wherein: R1 is selected from the group of substituents consisting of H, C1-C4 alkoxy C1-C2 alkyl, C3-C5 alkenyloxy C1-C2 alkyl, C3-C5 alkynyloxy C1-C2 alkyl, C1-C4 alkylthio C1-C2 alkyl, C1-C5 alkyl carbonyl, C3-C8 cycloalkyl carbonyl, C1-C5 alkoxy carbonyl or C1-C5 alkylthio carbonyl; R2 is Cl or methyl; R3 is H, methyl, CN, NO2 or halogen. The Formula I compounds have high insecticidal activities or acaricidal activities, and they can be used as pesticide or acaricide.
