Nitroenamine derivatives Novel nitroenamine derivatives of the formula I (I) in which R1 is hydrogen, C1-C6alkyl or C3-C6cycloalkyl, R2 is hydrogen or C1-C6alkyl, R3 is hydrogen, C1-C6alkyl or C3-C6cycloalkyl, R4 is hydrogen, C1-C6alkyl, C3-C6cycloalkyl or a radical -CH2-B, or R3 and R4 together are -(CH2)4- or -(CH2)5-; X is halogen or C1-C6haloalkyl; Y and Z are halogen; A is an unsubstituted or monosubstituted to tetrasubstituted aromatic or non-aromatic, monocyclic or bicyclic, heterocyclic radical in which one or two substituents belong to the group comprising C1-C3haloalkyl, cyclopropyl, halocyclopropyl, C2-C3alkenyl, C2-C3alkynyl, C2-C3haloalkenyl, C2-C3haloalkynyl, C1-C3haloalkoxy, C1-C3alkylthio, C1-C3haloalkylthio, allyloxy, propargyloxy, allylthio, propargylthio, haloallyloxy, haloallylthio, cyano and nitro and one to four substituents belong to the group comprising C1-C3alkyl, C1-C3alkoxy and halogen; B is phenyl, cyanophenyl, nitrophenyl, halophenyl having 1 to 3 halogen atoms, 3-pyridyl, 5-thiazolyl, or 5-thiazolyl which is substituted by one to two substituents from the group comprising C1-C3alkyl, C1-C3haloalkyl, cyclopropyl, halocyclopropyl, C2-C3alkenyl, C2-C3alkynyl, C1-C3alkoxy, C2-C3haloalkenyl, C2-C3haloalkynyl, C1-C3haloalkoxy, C1-C3alkylthio, C1-C3haloalkylthio, allyloxy, propargyloxy, allylthio, propargylthio, haloallyloxy, haloallylthio, halogen, cyano and nitro; or 3-pyridyl which is substituted by one to two radicals from the group comprising C1-C3haloalkyl, cyclopropyl, halocyclopropyl, C2-C3alkenyl, C2-C3alkynyl, C2-C3haloalkenyl, C2-C3haloalkynyl,C1-C3haloalkoxy, C1-C3alkylthio, C1-C3haloalkylthio, allyloxy, propargyloxy, allylthio, propargylthio, haloallyloxy, haloallylthio, cyano and nitro or by one to four radicals from the group comprising C1-C3alkyl, C1-C3alkoxy or halogen, and their salts with inorganic acids; it only being possible for one of the radicals R1, R3 and R4 to be hydrogen, and their salts can be used as pesticides. Insects and arachnids can preferably be controlled.
