2-Fluoroalkyl-substituted benzimidazoles, their preparation and their use as pesticides (2-Fluoroalkyl-substituted benzimidazoles, their preparation and their use as pesticides)

摘要

The present invention relates to novel substituted benzimidazoles of the general formula (I), their preparation and their use as pesticides.;Wherein R ¹ represents hydrogen, alkyl, halogenoalkyl, cycloalkyl or optionally substituted aryl, R ² represents hydrogen, alkyl, halogenoalkyl, cycloalkyl or optionally substituted aryl, and R ³ is fluoro Alkyl, X ¹ , X ² , X ³ and X ⁴ independently of one another in each case are hydrogen, halogen, cyano, nitro, in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsul Ponyl or cycloalkyl, optionally substituted and fused dioxyalkylene, hydroxycarbonyl, alkylcarbonyl, alkoxycarbonyl, cycloalkyloxycarbonyl, in each case optionally substituted amino or aminocarbonyl or in each case Aryl, aryloxy, aryl thio, arylsulfinyl, arylsulfonyl, arylsulfonyloxy, arylcarbonyl, aryloxycarbonyl, arylazo or arylthiomethylsulfonyl optionally substituted with At least one of these substituents X ¹ , X ² , X ³ and X ⁴ is not toil, except that compound 1 — (N, N-dimethylaminosulfonyl) -2-trifluoromethyl-4-nitro- 6-trifluoromethyl-benzoimidazole, 1- (N, N-dimethylaminosulfonyl) -2-trifluoromethyl-4-nitro-6-trifluoromethyl-benzoimidazole and 1- [N , N-bis- (n-propyl) -aminosulfonyl] -2-trifluoromethyl-4-nitro-6-trifluoromethyl-benzoimidazole is excluded.
