摘要

N-Phenyltetrahydroindazoles of formula (I), where R1 is H or C¿1-4?-alkyl; R?2¿ is halogen, C¿1-4?-alkyl or C1-4-haloalkyl; R?3¿ is H or halogen; R4 is NO¿2?, halogen, C1-4-alkyl or C1-4-haloalkyl; R?5 is -XR6¿; X is -O-, -S-, -SO- or -SO¿2-; R?6 is -Alk-R7; Alk is a substituted or unsubstituted methylene, ethylene, propylene, butylene or pentamethylene chain, where one chain member can carry a spiro-linked 2- to 5-membered C chain or where 2 ring members can be bridged via a C¿1-5?-alkylene chain; R?7¿ is CN, SCN, halogen or -YR11, where Y is -O-, -S-, -SO- or -SO¿2-; R?10 is H, OH, C¿1?-C4-alkyl, C1-C4-haloalkyl, C3-C5-cycloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, C3-C5-cycloalkoxy, C1-C4-alkylthio, C1-C4-haloalkylthio, -NH-R?12¿, -N(C¿1?-C4-alkyl)-R?12¿, -N(C¿3?-C4-alkenyl)-R?12¿, -N(C¿3?-C4-alkynyl)-R?12¿, pyrrolidin-1-yl, piperid-1-yl, morpholin-4-yl, azepan-1-yl, (i) unsubstituted or substituted phenyl, benzyl, phenoxy or benzyloxy; R11 is C¿1-6?-alkyl, C1-6-haloalkyl or C1-6-cycloalkyl; R?12¿ is H, OH, C¿1-4?-alkyl, C3-4-alkenyl, C3-4-alkynyl, C3-6-cycloalkyl, C1-4-alkoxy, C3-4-alkenyloxy, C3-4-alkenyloxy, C3-4-alkynyloxy, or substituted or unsubstituted phenyl or benzyl; and the agriculturally utilizable salts of formula (I), with the provisoes that the simultaneous meaning of R?6¿ as dihalomethyl, R?2 and R4¿ as chlorine and R3 as halogen is excluded; the simultaneous meaning of X as oxygen and R?7 as -OR11 or C¿1-C6-alkylthio is excluded; Alk must not carry a spiro-linked three-membered ring if R7 is halogen and R11 is not C¿1-6?-alkyl if R?1¿ is H, R2 is C¿1-4?-haloalkyl, R?3¿ is F, R4 is halogen and R?7 is -OR11¿. Use: as herbicides; for desiccating/defoliating plants.
