| 摘要 |
This invention concerns novel anilinomethylenemalononitrile derivatives corresponding to the formula I <IMAGE> (I) wherein R1 represents halogenalkyl containing 1 to 6 carbon atoms in the alkyl moiety, C3-C4 alkenyl, C3-C5 alkynyl or a benzyl radical which is unsubstituted or substituted by 1 to 2 halogen atoms, 1 to 2 C1-C2 alkyl radicals, or by a cyano or a trifluoromethyl group, R2 represents hydrogen, C1-C4 alkyl, halogen, the trifluoromethyl group, the nitro group or the cyano group, R3 represents hydrogen, halogen, the trifluoromethyl group or the nitro group, and R4 represents hydrogen or halogen, WITH THE PROVISO THAT, IF R1 represents the C3 alkynyl radical or the unsubstituted benzyl group, R2 and R3 may not be trifluoromethyl, compositions containing the novel compounds and the use of the novel compounds for combating helminths in domestic animals and productive livestock.
