Patent

CA 2277019

The invention concerns 5-(dioxabicyclohept-6-yl)-cyclohexenone oxime ethers of formula (I) in which the substituents have the following meanings: R1 is hydrogen, the equivalent of an agriculturally useful cation, C1-C10 alkylcarbonyl, C1-C10 alkylsulphonyl, C1-C10 alkylphosphonyl, benzoyl, benzene sulphonyl or benzene phosphonyl; R2 is C1-C6 alkyl; R3, in each case independently of each other, is hydrogen or C1-C4 alkyl; Z is a C1-C6 alkylene, C3-C6 alkenylene or C3-C6 alkinylene chain which can carry an exo- methylene substituent (=CH2) and/or in each case a further one to three substituents selected from a group comprising C1-C3 alkyl substituents and halogen atoms; a C3-C6 alkylene or C4-C6 alkenylene chain which can carry between one and three C1-C3 alkyl substituents and which, in addition to methylene or methine units, contains one of the following bridge members: oxygen, sulphur, -SO-, -SO2- or -N(Ri)-, Ri standing for hydrogen, C1-C4 alkyl, C3-C6 alkenyl or C3-C6 alkinyl; R4 is hydrogen, halogen, phenyl, wherein the phenyl group can be unsubstituted, partially or completely halogenated, and, if it is not completely halogenated, can carry between one and three substituents having the meaning given in the claims. The invention also concerns the preparation of these substances and their use.

L'invention concerne des éthers d'oxime de 5-(dioxabicyclohept-6-yle)cyclohexénone de la formule (I) dans laquelle les substituants ont la signification suivante: R?1¿ désigne hydrogène, l'équivalent d'un cation utilisable dans le domaine agricole, alkylcarbonyle C¿1?-C¿10?, alkylsulfonyle C¿1?-C¿10?, alkylphosphonyle C¿1?-C¿10?, benzoyle, sulfonyle de benzène ou phosphonyle de benzène; R?2¿ désigne alkyle C¿1?-C¿6?; les restes R?3¿ désignent dans chaque cas indépendamment les uns des autres, hydrogène ou alkyle C¿1?-C¿4?; Z désigne une chaîne alkylène C¿1?-C¿6?, alkénylène C¿3?-C¿6? ou alkinylène C¿3?-C¿6?, qui peut porter un substituant exo-méthylène (=CH¿2?) et/ou dans chaque cas, en outre, un à trois substituants, sélectionnés dans un groupe comprenant des substituants alkyle C¿1?-C¿3? et des atomes d'halogène; une chaîne alkylène C¿3?-C¿6? ou alkénylène C¿4?-C¿6? qui peut porter entre un et trois substituants alkyle C¿1?-C¿3? et contient, outre des unités méthylène ou méthine, un des membres de pontage suivants: oxygène, soufre, -SO-, -SO¿2?- ou N(R?i¿)-, R?i¿ désignant hydrogène, alkyle C¿1?-C¿4?, alkényle C¿3?-C¿6? ou alkinyle C¿3?-C¿6?; R?4¿ désigne hydrogène, halogène, phényle, le groupe phényle pouvant être non substitué, partiellement ou entièrement halogéné et, s'il n'est pas entièrement halogéné, pouvant porter entre un et trois substituants ayant la signification mentionnée dans les revendications. L'invention concerne également la préparation et l'utilisation desdits éthers.
