Abstract
The invention relates to novel compounds of formula I: wherein R, A, B and X have the meaning given in claim 1; and the agronomically acceptable salts or N-oxides thereof, and to herbicidal compositions containing such compounds as active ingredients.
Claims13
A compound of the formula (I):
- wherein
- A represents an optionally substituted aryl group or an optionally substituted 6-membered nitrogen-containing heteroaromatic group;
- B represents an optionally substituted phenyl or thienyl group;
- R represents a halogen atom or an optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkoxyalkyl, alkythio, alkylamino, dialkylamino, alkylsulphinyl, alkylsulphonyl group or a nitro, hydroxyl, amino, haloalkyl, haloalkoxy, haloalkylthio, or SF5 group, and
- X represents an oxygen or a sulfur atom;
- and the agronomically acceptable salts or N-oxides thereof.
