Substituted spiroheterocyclic 1H-3-aryl-pyrrolidine-2,4-dione derivatives, processes for their preparation, and their use as pesticides

摘要

The invention concerns substituted spiro heterocyclic 1H-3-arylpyrrolidine-2,4-dione derivatives depicted by the formula:X is alkyl, halogen or alkoxy; Y is hydrogen, alkyl, halogen, alkoxy or alkyl halide; Z is alkyl, halogen or alkoxy; n is 0, 1, 2 or 3; G is hydrogen (a) or one of the groups (b), (c), (d), (e), (f) or (g) as defined in the specification. The invention also concerns methods of preparing the substituted spiro heterocyclic 1H-3-arylpyrrolidine-2,4-dione derivative compounds, intermediate compounds thereof and use of substituted spiro heterocyclic 1H-3-arylpyrrolidine-2,4-dione derivative compounds as pest-control agents.
