The invention relates to a method for producing pyrazolylbenzoyl derivatives of formula (I), wherein the substituents have the following meanings: R1 represents hydrogen, C1-C4-alkyl or C1-C4 alkyl halide; R2 represents hydrogen, C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkinyl, benzyl, benzoyl, C1-C4- alkylcarbonyl, hydroxycarbonyl-C1-C4-alkyl, C1-C4-alkoxycarbonyl-C1-C4-alkyl, C1-C4-alkylsulfonyl or phenylsulfonyl, and these groups can be substituted by C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkylthio, halogen, hydroxy, amino, nitro or cyano; A,B represent, independently of each other, hydrogen, C1-C6-alkyl, C2- C6-alkenyl, C2-C6-alkinyl, C1-C4-alkoxy and these groups can be substituted by halogen, hydroxy, C1-C4-alkoxy or cyano, halogen, hydroxy, cyano; nitro, a group-(Y)n-S(O)mR3 or a group-(Y)n-CO-R4; Z represents a 5- or 6-membered heterocyclic, saturated or unsaturated fused ring; Y represents O, NR5; n represents zero or one; m represents zero, one or two; R3 represents C1-C4- alkyl, C1-C4-alkyl halide or NR5R6; R4 represents C1-C4-alkyl, C1-C4-alkyl halide, C1-C4-alkoxy, or NR5R6; R5 represents hydrogen or C1-C4-alkyl; and R6 represents C1-C4-alkyl. The invention also relates to novel pyrazolylbenzoyl derivatives, to herbicidal agents containing these derivatives and to a method for combating unwanted vegetation.
La présente invention concerne un procédé pour la production de dérivés de pyrazolylbenzoyle de la formule (I) dans laquelle les substituants ont la signification suivante: R?1¿ est hydrogène, alkyle C¿1?-C¿4? ou bien halogénoalkyle C¿1?-C¿4?; R?2¿ est hydrogène; alkyle C¿1?-C¿6?, alcényle C¿2?-C¿6?, alcynyle C¿2?-C¿5?, benzyle, benzoyle, alkyle C¿1?-C¿4?-carbonyle, hydroxycarbonylalkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?-carbonylalkyle C¿1?-C¿4?, alkyle C¿1?-C¿4?-sulfonyle ou bien phénylsulfonyle, ces groupes pouvant être substitués par alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?, alkyle C¿1?-C¿4?-thio, halogène, hydroxy, amino, nitro ou cyano; A, B sont indépendamment l'un de l'autre hydrogène; alkyle C¿1?-C¿6?, alcényle C¿2?-C¿6?, alcynyle C¿2?-C¿6?, alcoxy C¿1?-C¿4?, ces groupes pouvant être substitués par halogène, hydroxy, alcoxy C¿1?-C¿4? ou bien cyano; halogène, hydroxy, cyano, nitro, un groupe -Y)¿n?-SE(O)¿m?R?3¿ ou bien un groupe -Y)¿n?-CO-R?4¿; Z est un noyau fusionné hétérocyclique pentagonal ou hexagonal, saturé ou insaturé; Y est O, NR?5¿; n vaut 0 ou 1; m vaut 0, 1 ou 2; R?3¿ est alkyle C¿1?-C¿4?, halogénoalkyle C¿1?-C¿4? ou bien NR?5¿R?6¿; R?4¿ est alkyle C¿1?-C¿4?, halogénoalkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?, ou bien NR?5¿R?6¿; R?5¿ est hydrogène ou alkyle C¿1?-C¿4?; R?6¿ est alkyle C¿1?-C¿4?. L'invention concerne également de nouveaux dérivés de pyrazolylbenzoyle, des agents herbicides les contenant, ainsi qu'un procédé pour lutter contre la croissance végétale parasite.
