New herbicidal compounds are provided having formula (II) wherein Y is oxygen or sulfur; R1 and R2 are each independently a C1-14 hydrocarbyl group, unsubstituted or substituted with one or more halogen, haloalkyl, hydroxy, alkoxy, carboxy, amido, cyano or amino groups; or R1 and R2, together with the carbamoyl nitrogen atom to which they are attached, form a nitrogen-containing five or six membered ring, the ring being optionally interrupted by an ethereal oxygen atom and unsubstituted or substituted with one or more hydroxy, amido, cyano, amino or C1-8 alkyl, alkenyl, alkynyl, cycloalkyl, arylalkyl, alkoxy, aminoalkyl or haloalkyl groups; and R3 is hydrogen, halogen, or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, cycloalkylalkenyl, aryl, arylalkyl, alkylthio or arylalkythio group that is unsubstituted or substituted with one or more halo, hydroxy, alkoxy, acetyloxy, benzoyloxy, alkoxycarbonyl, silyl or alkylsilyl groups, or an agronomically acceptable acid addition salt or metal complex of such compound.

L'invention concerne de nouveaux composés herbicides correspondant à la formule (II) dans laquelle Y est oxygène ou soufre; R?1¿ et R?2¿ sont chacun indépendamment un groupe hydrocarbyle C¿1-14?, substitué ou non substitué par un ou plusieurs éléments parmi des groupes halogène, haloalkyle, hydroxy, alcoxy, carboxy, amido, cyano ou amino; ou R?1¿ et R?2¿, avec l'atome d'azote du carbamoyle auquel il sont attachés, forment un noyau à cinq ou six éléments contenant l'azote, le noyau étant éventuellement interrompu par un atome d'oxygène de l'éther et substitué ou non substitué par un ou plusieurs éléments parmi des groupes hydroxy, amido, cyano, amino ou alkyle C¿1-8?, alkynyle, cycloalkyle, arylalkyle, alcoxy, aminoalkyle ou haloalkyle; et R?3¿ est hydrogène, halogène, ou un groupe alkyle, cycloalkyle, alcényle, cycloalcényle, cycloalkylalcényle, aryle, arylalkyle, alkylthio ou arylalkylthio qui est substitué ou non substitué par un ou plusieurs éléments parmi des groupes halo, hydroxy, alcoxy, acétyloxy, benzoyloxy, alcoxycarbonyle, silyle ou alkylsilyle, ou un sel d'addition d'un acide acceptable en agronomie ou un complexe métallique de ce composé.
