Patent

CA 2233258

The invention concerns phenylacetic acid derivatives of formula (I), in which the variables have the following meanings: X = NOCH3, CHOCH3 or CHCH3; Y = O or NZ, Z standing for hydrogen or alkyl; R1 = H or alkyl; R2 = cyano, nitro, trifluoromethyl, halogen, alkyl or alkoxy; m = 0, 1 or 2, wherein the group R2 can be different when m = 2; R3 = H, cyano, alkyl, alkyl halide, alkoxy or cyclopropyl; R4 = alkylenedioxy, the alkylene groups being partially or completely halogenated, or one of the groups: -(C=O)-Ra, -C(=NORa)-Ap-Rb, -NRc- (C=O)-Ap-Ra, -O-(C=O)-NRaRb or -N(Rc)-ORd, Ra, Rb, independently of each other, being H or optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl; Rc, Rd, independently of each other, being H or optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkenylcarbonyl, alkinylcarbonyl, alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, cycloalkyl, cycloalkylcarbonyl, cycloalkyloxycarbonyl, arylcarbonyl or heteroarylcarbonyl; p = 0 or 1; A = O, S or N, the N-atom carrying H or alkyl; n = 1 or 2, wherein the group R4 can be different when n = 2; and R5 = H, alkylsulphonyl or optionally substituted alkyl, alkenyl, alkinyl or cycloalkyl. The invention further concerns salts of these substances, a process and intermediate products for their preparation, and their use as fungicides and pesticides.

L'invention concerne des dérivés d'acide phénylacétique de la formule (I) dans laquelle les variables ont les notations suivantes: X désigne NOCH3, CHOCH3 ou ChCH3; Y désigne O ou NZ, Z désignant hydrogène ou alkyle; R<1> désigne H ou alkyle; R<2> désigne cyano, nitro, trifluorométhyle, halogène, alkyle ou alcoxy; m vaut 0, 1 ou 2, les restes R<2> pouvant être identiques ou différents si m=2; R<3> désigne H, cyano, halogénure d'alkyle, alcoxy ou cyclopropyle; R<4> désigne alkylènedioxy, les groupes alkylène étant halogénés partiellement ou complètement, ou un des restes: -(C=O)-R<a>, -C(=NOR<a>)-Ap-R<b>, -NR<c>-(C=O)-Ap-R<a>, -O-(C==O)-NR<a>R<b> ou -N(R<c>)-OR<d>, R<a>, R<b> = indépendamment l'un de l'autre, H ou alkyle, alkényle, alkinyle, cycloalkyle, cycloalkényle, hétérocyclyle, aryle ou hétéroaryle éventuellement substitués; R<c>, R<d> = indépendamment l'un de l'autre, H ou alkyle, alkényle, alkinyle, alkylcarbonyle, alkénylcarbonyle, alkinylcarbonyle, alcoxycarbonyle, alkényloxycarbonyle, alkinyloxycarbonyle, c ycloalkyle, cycloalkylcarbonyle, cycloalkyloxycarbonyle, arylcarbonyle ou hétéroarylcarbonyle éventuellement substitués; p = 0 ou 1; A = O, S ou N, l'atome de N portant H ou alkyle; n vaut 1 ou 2, les restes R<4> pouvant être différents si n = 2; R<5> désigne H, alkylesulfonyle ou alkyle, alkényle, alkinyle ou cycloalkyle éventuellement substitués. L'invention concerne également leurs sels, des procédés et des produits intermédiaires permettant de les préparer et leur utilisation pour lutter contre les champignons nuisibles et les parasites animaux.
