Patent

CA 2225248

Compounds of Formula (I), and their agriculturally suitable salts, are disclosed which are useful for controlling undesired vegetation wherein Q is (Q-1) or (Q-2); R1 and R2 are each independently C1-C6 alkoxy, C2-C6 haloalkoxy, C1-C6 alkylthio or C2-C6 haloalkylthio; or R1 and R2 are taken together to form -X1-(CH2)r-X2-, -(CH2)s-X3-, -(CH2)t-X3-CH2-, -(CH2)v-X3- CH2CH2- or -(CH2)w-, each group optionally substituted with at least one member selected from 1-6 halogen, 1-6 CH3 and one C1-C3 alkoxy; or R1 and R2 are taken together to form -O-N(C1-C3 alkyl)-CHR12-CH2- or -O-N=CHR12-CH2-, each group optionally substituted with at least one member selected from 1-2 halogen and 1-2 CH3; or R1 and R2 are taken together with the carbon to which they are attached to form C(=O) or C(=S); and R3-R10, X1-X3, X, Y, Z, k, m, p, q, r, s, t, v, w, and x are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (I) and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula (I).

Pour lutter contre une végétation indésirable, on décrit des composés de formule (I), ainsi que leurs sels appropriés à un usage agricole, formule dans laquelle Q représente (Q-1) ou (Q-2); R?1¿ et R?2¿ représentent chacun indépendemment alkoxy C¿1?-C¿6?, haloalkoxy C¿2?-C¿6?, alkylthio C¿1?-C¿6? ou haloalkylthio C¿2?-C¿6?; ou bien R?1¿ et R?2¿ forment conjointement -X?1¿-(CH¿2?)¿r?-X?2¿-, -(CH¿2?)¿s?-X?3¿-, -(CH¿2?)¿t?-X?3¿-CH¿2?-, -(CH¿2?)¿v?-X?3¿-CH¿2?CH¿2?- ou -(CH¿2?)¿w?-, chacun de ces groupes étant éventuellement substitué par au moins un élément choisi parmi 1-6 halogène, 1-6 CH¿3? et un alkoxy C¿1?-C¿3?; ou bien R?1¿ et R?2¿ forment ensemble -O-N(alkyl C¿1?-C¿3?)-CHR?12¿-CH¿2?- ou -O-N=CHR?12¿-CH¿2?-, chacun de ces groupes étant éventuellement substitué par au moins un élément choisi entre 1-2 halogène et 1-2 CH¿3?; ou bien R?1¿ et R?2¿ forment ensemble et avec le carbone auquel ils sont fixés C(=O) ou C(=S); et R?3¿-R?10¿, X?1¿-X?3¿, X, Y, Z, k, m, p, q, r, s, t, v, w, et x correspondant à leur description. On décrit aussi des compositions contenant des composés de formule (I) et un procédé permettant de lutter contre une végétation indésirable et consistant à mettre celle-ci ou son environnement en contact avec une quantité efficace d'un composé de formule (I).
