Hydroxylamine derivatives have the general formula I Aryl-A-O-B I where Aryl is an unsubstituted or substituted, mononuclear or binuclear, isocyclic radical; A is a 1,4-butenylene group of the general formulae IIa or IIb <IMAGE> IIa <IMAGE> IIb where R1, R2, R3, R4 and R5 are each hydrogen, halogen, C1-C6-alkyl or C1-C6-alkenyl; B is NH2 or a dicarboximide group of the general formula III <IMAGE> III where Z is unsubstituted or substituted phenylene, naphthylene, pyridinylene, cyclopentylene, cyclohexylene, cyclohexenylene, C2-C4-alkenylene or C2-C4-alkylene. The dicarboximides are intermediates for the compounds wherein B is NH2. The latter are used in synthesizing herbicidal compounds. |
