ABSTRACT:
Substituted isoxazolines, process for their preparation, compositions containing them, and their use as safeners.
Compounds of the formula (I) and salts thereof, ##STR1## in which R.sup.1 is carboxyl, formyl or another acyl radical or a derivative of the last-mentioned 3 groups,
R.sup.2 is hydrogen, halogen, C.sub.1 -C.sub.18 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, C.sub.2 -C.sub.8 -alkenyl, C.sub.2 -C.sub.8 -alkynyl, C.sub.1 -C.sub.18 -alkoxy, C.sub.2 -C.sub.8 -alkenyloxy, C.sub.2 -C.sub.8 -alkynyloxy, C.sub.1 -C.sub.18 -alkylthio, C.sub.2 -C.sub.8 -alkenylthio, each of the last-mentioned 9 radicals in each case being unsubstituted or substituted, or (C.sub.1 -C.sub.8 -alkoxy)carbonyl, and
R.sup.3 and R.sup.4 independently of one another are an aliphatic, araliphatic or heteroaraliphatic radical having 1 to 30 carbon atoms which is unsubstituted or substituted by one or more functional groups, or
an aromatic or heteroaromatic radical which is unsubstituted or substituted,
are suitable as safenets for pesticides, preferably herbicides, in crop plants. The compounds can be prepared from alkenes (II) and nitrile oxides (III) by the process of claim 6.
