CA 2304270

The invention relates to benzamidoxim derivatives of formula (I) wherein the substituents have the following meanings: R1 represents difluoromethyl or trifluoromethyl, R2 represents hydrogen or fluorine, R3 represents C1-C4 alkyl optionally substituted with cyano, C1-C4 halogenalkyl, C1-C4 alkoxy- C1-C4 alkyl, C3-C6 alkenyl, C3-C6 halogenalkenyl, C3-C6 alkinyl, C3-C8 cycloalkyl- C1-C4 alkyl, R4 represents phenyl- C1-C6 alkyl, which can carry one or more substituents selected from the group composed of halogen, C1-C4 alkyl, C1-C4 halogenalkyl, C1-C4 alkoxy or C1-C4 halogenalkoxy on the phenyl ring, or thienyl- C1-C4 alkyl, which can carry one or more substituents selected from the group composed of halogen, C1-C4 alkyl, C1-C4 halogenalkyl, C1-C4 alkoxy or C1-C4 halogenalkoxy on the thienyl ring, or pyrazol- C1-C4 alkyl, which can carry one or more substituents selected from the group composed of halogen, C1- C4 alkyl, C1-C4 halogenalkyl, C1-C4 alkoxy or C1-C4 halogenalkoxy on the pyrazol ring. The invention also relates to intermediate products for the preparation of these derivatives and to their use as fungicides.

L'invention concerne des dérivés de benzamidoxime de la formule (I) où les substituants ont les significations suivantes: R?1¿ désigne difluorométhyle ou trifluorométhyle, R?2¿ désigne hydrogène ou fluor, R?3¿ désigne alkyle C¿1?-C¿4? pouvant être substitué par cyano, halogénure d'alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4?-alkyle C¿1?-C¿4?, alkényle C¿3?-C¿6?, halogénure d'alkényle C¿3?-C¿6?, alkinyle C¿3?-C¿6?, cycloalkyle C¿3?-C¿8?-alkyle C¿1?-C¿4?, R?4¿ désigne phényle-alkyle C¿1?-C¿6? qui peut porter sur le composé cyclique phényle un ou plusieurs substituants sélectionnés dans le groupe comprenant halogène, alkyle C¿1?-C¿4?, halogénure d'alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4? ou halogénure d'alcoxy C¿1?-C¿4?, ou thiényle-alkyle C¿1?-C¿4? qui peut porter sur le composé cyclique thiényle un ou plusieurs substituants sélectionnés dans le groupe comprenant halogène, alkyle C¿1?-C¿4?, halogénure d'alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4? ou halogénure d'alcoxy C¿1?-C¿4?, ou pyrazol-alkyle C¿1?-C¿4? qui peut porter sur le composé cyclique pyrazol un ou plusieurs substituants sélectionnés dans le groupe comprenant halogène, alkyle C¿1?-C¿4?, halogénure d'alkyle C¿1?-C¿4?, alcoxy C¿1?-C¿4? ou halogénure d'alcoxy C¿1?-C¿4?. L'invention concerne en outre des produits intermédiaires utilisés pour préparer lesdits dérivés de benzamidoxime, ainsi que leur utilisation comme fongicides.
