ABSTRACT:
Heterocyclically substituted phenoxysulfonylureas, processes for the preparation thereof, and the use thereof as herbicides or plant growth regulators. Compounds of the formula I or the salts thereof ##STR1## where R.sup.1 is (C.sub.1 -C.sub.8)alkyl, (C.sub.2 -C.sub.8)alkenyl or (C.sub.2 -C.sub.8)alkynyl, these radicals being substituted by halogen, saturated or unsaturated (C.sub.1 -C.sub.6)alkoxy, (C.sub.1 -C.sub.6)alkylthio, -sulfinyl or -sulfonyl, (C.sub.1 -C.sub.6)alkoxycarbonyl, NO.sub.2, CN or phenyl; furthermore is (C.sub.2 -C.sub.8)alkenyl, (C.sub.2 -C.sub.8)alkynyl or (C.sub.3 -C.sub.8)cycloalkyl, which can be substituted by halogen or by alkoxy or alkylthio; (C.sub.5 -C.sub.8)cycloalkenyl, cyclopropylmethyl, epoxypropyl; furfuryl, tetrahydrofurfuryl or phenoxy (C.sub.1 -C.sub.4)alkyl, it being possible for the last three substituents mentioned to be substituted by halogen, alkyl or alkoxy; or phenyl which can be substituted by halogen, alkyl, alkoxy, NO.sub.2, CF.sub.3, CN or OCHF.sub.2 ; or, in the event that R.sup.2 is alkenyl, alkynyl, phenyl or phenoxy, each of which can be substituted as indicated below, alkylsulfonyl or alkylsulfinyl and n.noteq., R.sup.1 is also (C.sub.1 -C.sub.8)alkyl,
