Substituted 1H--3-aryl-pyrrolidine-2,4-dione derivatives

A 1H-3-aryl-pyrrolidine-2,4-dione derivative of the formula (I) ##STR323## in which A represents hydrogen, or alkyl, alkenyl, alkoxyalkyl or alkylthioalkyl, each of which is optionally substituted by halogen, or cycloalkyl which is optionally interrupted by at least one hetero atom selected from oxygen or sulfur and optionally substituted, or aryl, arylalkyl or hetaryl, each of which is optionally substituted by 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 cycle which is optionally interrupted by at least one hetero atom selected from oxygen or sulfur,
• one of X and Y represents halogen and the other represents alkyl,
• G represents hydrogen (a) or one of the groups ##STR324## E represents a metal ion equivalent or an ammonium ion, L and M represent in each case oxygen or sulfur,
• R.sup.1 represents alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl or polyalkoxyalkyl, each of which is optionally substituted by halogen, or cycloalkyl which is optionally substituted by halogen or alkyl and can be interrupted by at least one hetero atom, or in each case optionally substituted phenyl, phenylalkyl, hetaryl, phenoxyalkyl or hetaryloxyalkyl,
• R.sup.2 represents alkyl, alkenyl, alkoxyalkyl or polyalkoxyalkyl, each of which is optionally substituted by halogen, or in each case optionally substituted cycloalkyl, phenyl or benzyl,
• R.sup.3, R.sup.4 and R.sup.5 independently of one another represent alkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkenylthio or cycloalkylthio, each of which is optionally substituted by halogen, or in each case optionally substituted phenyl, phenoxy or phenylthio, and
• R.sup.6 and R.sup.7 independently of one another represent hydrogen, or alkyl, cycloalkyl, alkenyl, alkoxy or alkoxyalkyl, each of which is optionally substituted by halogen, or in each case optionally substituted phenyl or benzyl, or together with the N atom to which they are bonded a cycle which is optionally interrupted by oxygen or sulfur,
• a diastereomer mixture, pure diastereomer or enantiomer thereof wherein hetaryl, above, is a membered selected from the group consisting of furanyl, pyridyl, imidazolyl, pyrazolyl, triazolyl, indolyl, thiazolyl, thienyl, or pyrimidinyl.
