Abstract

N-phenyltetrahydrophthalimides of the formula I ##STR1## where R.sup.1 is hydrogen or halogen, R.sup.2 is halogen and A is a substituent of the formula ##STR2## where X is oxygen or sulfur, n is zero or one, R.sup.3 is hydrogen or C.sub.1 -C.sub.6 -alkoxycarbonyl or C.sub.1 -14 C.sub.3 -alkyl which is unsubstituted or substituted by halogen, cyano, hydroxyl, mercapto, C.sub.1 -C.sub.6 -alkoxycarbonyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.3 -C.sub.6 -alkenyloxy, C.sub.3 -C.sub.6 -alkenylthio, C.sub.3 -C.sub.6 -alkynyloxy, C.sub.3 -C.sub.6 -alkynylthio or C.sub.1 -C.sub.4 -acyloxy, or is hydroxyl or carboxyl or is C.sub.1 -C.sub.4 -alkylthio-C.sub.1 - or C.sub.2 -alkyl or C.sub.1 -C.sub.4 -alkoxy-C.sub.1 - or -C.sub.2 -alkyl which is substituted in the alkyl ether or thioehter moiety by C.sub.1 -C.sub.6 -alkoxycarbonyl, R.sup.4 is hydrogen or C.sub.1 -C.sub.3 -alkyl, Z is methyleneoxymethylene, methylenethiomethylene or ethenylene (--CH.dbd.CH--) and R.sup.5 and R.sup.6 are each hydrogen or C.sub.1 -C.sub.3 -alkyl, which are useful as herbicides, are prepared.
