Abstract
The present invention relates to novel 1H-3-aryl-pyrrolidine-2,4-dione derivatives of the formula (I) ##STR1## in which A, B, G, X, Y and Z have the meaning given in the description, to processes for their preparation and to intermediates for this purpose. The compounds of the formula (I) are used as pesticides and herbicides.
Claims10
A 1H-3-Aryl-pyrrolidine-2,4-dione compound of the formula (I) ##STR440## in which A represents hydrogen, in each case optionally halogeno-substituted alkyl, alkenyl, alkoxyalkyl, polyalkoxyalkyl or alkylthioalkyl, cycloalkyl which is optionally interrupted by at least one heteroatom and optionally substituted, or represents in each case optionally halogen-, alkyl-, halogenoalkyl-, alkoxy- or nitro-substituted aryl, arylalkyl or hetaryl,
- B represents alkyl or alkoxyalkyl, or
- A and B together with the carbon atom to which they are attached represent a saturated or unsaturated, unsubstituted or substituted ring which is optionally interrupted by at least one heteroatom,
- X represents alkyl or alkoxy,
- Y represents hydrogen, alkyl or alkoxy,
- Z represents hydrogen, alkyl or alkoxy,
- G represents hydrogen (a) or represents the groups ##STR441## E represents a metal ion equivalent or an ammonium ion, L represents oxygen or sulfur,
- M represents oxygen or sulfur,
- R.sup.1 represents in each case optionally halogeno-substituted alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl or polyalkoxyalkyl, or optionally halogen- or alkyl-substituted cycloalkyl which may be interrupted by at least one heteroatom, or represents in each case optionally substituted phenyl, phenylalkyl, hetaryl, phenoxyalkyl or hetaryloxyalkyl,
- R.sup.2 represents in each case optionally halogeno-substituted alkyl, alkenyl, alkoxyalkyl or polyalkoxyalkyl, or represents in each case optionally substituted cycloalkyl, phenyl or benzyl,
- R.sup.3, R.sup.4 and R.sup.5 independently of one another represent in each case optionally halogeno-substituted alkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkenylthio or cycloalkylthio or represent in each case optionally substituted phenyl, phenoxy or phenylthio,
- R.sup.6 and R.sup.7 independently of one another represent hydrogen, represent in each case optionally halogeno-substituted alkyl, cycloalkyl, alkenyl, alkoxy or alkoxyalkyl, represent optionally substituted phenyl, represent optionally substituted benzyl, or together with N atom to which they are attached represent a ring which is optionally interrupted by oxygen or sulfur,
- with the proviso that at least one of the substituents Y and Z represents alkoxy if X represents alkyl.
