Abstract

N-Phenyltetrahydroindazoles of formula (I), where R.sub.1 is H or C.sub.1-4 -alkyl; R.sup.2 is halogen, C.sub.1-4 -alkyl or C.sub.1-4 -haloalkyl; R.sup.3 is H or halogen; R.sup.4 is NO.sub.2, halogen, C.sub.1-4 -alkyl or C.sub.1-4 -haloalkyl; R.sup.5 is --XR.sup.6 ; X is --O--, --S--, --SO-- or --SO.sub.2 --; R.sup.6 is --Alk--R.sup.7 ; 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.sub.1-5 -alkylene chain; R.sup.7 is CN, SCN, halogen or --YR.sup.11, where Y is --O--, --S--, --SO-- or --SO.sub.2 --; R.sup.10 is H, OH, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.3 -C.sub.5 -cycloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.3 -C.sub.5 -cycloalkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio, --NH--R.sup.12, --N(C.sub.1 -C.sub.4 -alkyl)--R.sup.12, --N(C.sub.3 -C.sub.4 -alkenyl)-R.sup.12, --N(C.sub.3 -C.sub.4 -alkynyl)-R.sup.12, pyrrolidin-1-yl, piperid-1-yl, morpholin-4-yl, azepan-1-yl, (i) unsubstituted or substituted phenyl, benzyl, phenoxy or benzylox…
