Patent

CA 2188772

Compounds of formula (I) and (II), and their agriculturally-suitable salts, are disclosed which are useful for controlling undesired vegetation, wherein X is a direct bond, O, S, NH, N(C1-C3 alkyl), N(C1-C3 haloalkyl) or N(allyl); R1 is H, F, Cl, or Br; R2 is H, F, Cl, Br, CF3, nitro, or cyano; R4 is H, C1-C3 alkyl, or halogen; R5 is H, C1-C6 alkyl, C1-C6 haloalkyl, halogen, S(O)2(C1-C6 alkyl), or C(=O)R8; or R4 and R5 are taken together along with the carbon to which they are attached to form a spiro-cyclopropane ring; and R3, R8, and J are as defined in the disclosure. Also disclosed are compositions containing the compounds of formulae (I) and (II) 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) or (II).

On décrit des composés de formule (I) et (II), et leurs sels appropriés à l'agriculture, utiles pour lutter contre la végétation indésirable, où X représente une liaison directe, O, S, NH, N(C¿1-3? alkyle), N(C¿1-3? haloalkyle) ou N(allyle); R?1¿ représente H, F, Cl ou Br; R?2¿ représente H, F, Cl, Br, CF¿3?, nitro ou cyano; R?4¿ représente H, C¿1-3? alkyle ou halogène; R?5¿ représente H, C¿1-6? alkyle; C¿1-6? haloalkyle; halogène; S(O)¿2?(C¿1-6? alkyle); ou C(=O)R?8¿; ou bien R?4¿ et R?5¿ ensemble, avec l'atome de carbone auquel ils sont rattachés, forment un cycle spiro-cyclopropane; et R?3¿, R?8¿ et J correspondent à la description. On décrit aussi des compositions contenant des composés des formules (I) et (II) et un procédé qui permet de lutter contre la végétation indésirable et consiste à mettre celle-ci ou son environnement en contact avec une quantité efficace d'un composé de formule (I) ou (II).
