Abstract
The invention relates to new 1H-3-aryl-pyrrolidine-2,4-dione derivatives of the formula (I) ##STR1## in which A, B, X, Y and G have the meanings given in the description, to a plurality of processes for their preparation, and to their use as pesticides.
Claims7
An acyl-amino ester of the formula ##STR323## in which A represents hydrogen, alkyl, alkenyl, alkoxyalkyl or alkylthioalkyl, each of which is optionally substituted by substituents selected from the group consisting of halogen, cycloalkyl optionally substituted aryl, and optionally substituted arylalkyl wherein the optional substituents are substituents selected from the group consisting of halogen, alkyl, halogenoalkyl, alkoxy and nitro,
- B represents hydrogen, alkyl or alkoxyalkyl, or
- A and B together with the carbon atom to which they are bonded represent a saturated or unsaturated, unsubstituted or substituted 5 or 6 member cycle,
- X represents halogen or alkyl,
- Y represents halogen or alkyl, and
- R.sup.8 represents alkyl,
- provided that one X and Y represents halogen and the other represents alkyl.
A compound of the formula ##STR324## in which A represents hydrogen, or alkyl, alkenyl, alkoxyalkyl or alkylthioalkyl, each of which is optionally substituted by halogen, cycloalkyl
- optionally substituted aryl, and optionally substituted arylalkyl
- wherein the optional substituents are halogen, alkyl, halogenoalkyl, alkoxy or nitro,
- B represents hydrogen, alkyl or alkoxyalkyl, or
- A and B together with the carbon atom to which they are bonded represent a saturated or unsaturated, unsubstituted or substituted 5 or 6 member cycle,
- X represents halogen or alkyl,
- Y represents halogen or alkyl, and
- provided that one of X and Y represents halogen and the other represents alkyl.
