Patent

CA 2281688

Novel herbicidal compounds, compositions containing them, and methods for their use in controlling weeds are disclosed. The novel herbicidal compounds are represented by formula (I), where J is a 1-substituted-6-trifluoromethyl- 2,4-pyrimidinedione-3-yl, a 1-substituted-6-trifluoromethyl-1,3,5-triazine-2,4- dion-1-yl, a 3,4,5,6-tetrahydrophthalimid-1-yl, a 4-difluoromethyl-4,5-dihydro- 3-methyl-1,2,4-triazol-5(1H)-on-1-yl, a 5,6,7,8-tetrahydro-1H,3H- [1,3,4]thiadiazolo[3,5-a]pyridazineimin-1-yl, or a 1,6,8-triazabicyclo[4.3.0]- nonane-7,9-dion-8-yl ring attached at the 7 position of a benzofuran, benzoxazole, indole, 2,3-dihydrobenzimidazole or benzimidazole, and X is selected from hydrogen, halogen, cyano, nitro, and amino. Preferred R groups are optionally substituted alkyl groups.

Cette invention se rapporte à de nouveaux composés herbicides, à des compositions contenant ces composés et à des procédés pour leur utilisation dans la lutte contre les mauvaises herbes. Ces nouveaux composés herbicides sont représentés par la formule (1), où J représente un anneau 1-substitué-6-trifluorométhyle-2,4-pyrimidinedione-3-yle, un anneau 1-substitué-6-trifluorométhyl-1,3,5-triazine-2,4-dion-1-yl, un anneau 3,4,5,6-tétrahydrophthalimide-1-yl, un anneau 4-difluorométhyl-4,5-dihydro-3-méthyl-1,2,4-triazol-5(1H)-on-1-yl, or a 1,6,8-tétrahydro-1H,3H-[1,3,4]thiadiazolo[3,5-a]pyridazineimin-1-yl, ou un anneau 1,6,8-triazabicyclo[4.3.0]-nonane-7,9-dion-8-yl, fixé à la position 7 d'un benzofuranne, d'un benzoxazole, d'un indole, d'un 2,3-dihydrobenzimidazole ou d'un benzimidazole, et X est choisi parmi hydrogène, halogène, cyano, nitro et amino. Les groupes R préférés sont des groupes alkyle éventuellement substitués.
