Patent

CA 2394422

Disclosed are phenoxy and thiophenoxy acrylic acid compounds of general formula (I), wherein Z, V and W, independently from one another, mean oxygen or sulphur and Het stands for an unsaturated, five- or six-membered, heterocyclic radical which is linked to a phenyl ring of formula (I) via a nitrogen atom. The invention also relates to methods for producing the same and to intermediate products for the production thereof. The invention further relates to herbicidally effective means which contain the compounds of formula (I) and a method for combating harmful plants.

La présente invention concerne des composés d'acide phénoxyacrylique et thiophénoxyacrylique, de formule générale (I), dans laquelle Z, V et W représentent, indépendamment les uns des autres, oxygène ou soufre et Het représente un reste hétérocyclique à cinq ou six éléments, insaturé, qui est lié à un cycle phénylique de la formule (I), par l'intermédiaire d'un atome d'azote. La présente invention concerne également des procédés de production de ces composés, des produits intermédiaires pour cette production, des agents herbicides contenant les composés de formule (I), ainsi qu'un procédé permettant de lutter contre les végétaux nuisibles.
