    Abstract: PURPOSE: Herbicidal2-(5-oxiranylmethoxyphenyl)-4,5,6,7-tetrahydro-2H-indazole derivatives are provided, which compounds have improved herbicidal effects and selectivity, so that the compounds can selectively kill weeds. CONSTITUTION: The herbicidal2-(5-oxiranylmethoxyphenyl)- 4,5,6,7-tetrahydro-2H-indazole derivatives represented by formula (1) are provided, wherein R1, R2 and R3 are independently hydrogen, C1-C5 alkyl, phenyl or substituted phenyl with 1 to 3 of halogen atoms. The method for preparing the herbicidal2-(5-oxiranylmethoxyphenyl)- 4,5,6,7-tetrahydro-2H-indazole derivatives of formula (1) comprises the steps of: reacting a compound of formula (2) with allyl halide in the presence of base to prepare a compound of formula (3); and introducing epoxy group into a double bond of the compound of formula (3), wherein X is halogen.
