The invention relates to novel substituted n-aryl-o-aryloxyalkyl carbamates of general formula (I), wherein m represents the numbers 0, 1 or 2, n represents the numbers 0, 1, 2, 3 or 4, R1 represents cyano, halogen or alkyl or alkoxy, said alkyl or alkoxy being optionally substituted by cyano, halogen or C1-C4 alkoxy and each having 1 to 4 carbon atoms; R2 represents alkyl optionally substituted by cyano, halogen or C1-C4 alkoxy and each having 1 to 4 carbon atoms, R3 represents cyano, fluorine, bromine, iodine or alkyl, alkoxy or alkoxy carbonyl optionally substituted by cyano, halogen or C1-C4 alkoxy, each having up to 4 carbon atoms; and R4 represents cyano, bromine, iodine or alkyl, alkoxy or alkoxy carbonyl optionally substituted by cyano, halogen or C1-C4 alkoxy, each having up to 4 carbon atoms, excluding the compound N-(2- methoxy-5-methyl-phenyl)-O-[1-(3-trifluoromethyl-phenoxymethyl)-propyl]- carbamate. The invention also relates to methods for producing the inventive substituted n-aryl-o-aryloxyalkyl carbamates and to their use as herbicides.
L'invention concerne de nouveaux N-aryle-O-aryloxyalkyle-carbamates substitués de la formule générale (I) dans laquelle m vaut 0, 1 ou 2, n vaut 0, 1, 2, 3 ou 4, R?1¿ désigne cyano, halogène, ou alkyle ou alcoxy dans chaque cas éventuellement substitué par cyano, halogène ou alcoxy C¿1?-C¿4? et comportant chacun entre 1 et 4 atomes de carbone, R?2¿ désigne alkyle éventuellement substitué par cyano, halogène ou alcoxy C¿1?-C¿4? et comportant entre 1 et 4 atomes de carbone, R?3¿ désigne cyano, fluor, brome, iode ou alkyle, alcoxy ou alcoxycarbonyle éventuellement substitué dans chaque cas par cyano, halogène ou alcoxy C¿1?-C¿4? et comportant chacun entre 1 et 4 atomes de carbone, et R?4¿ désigne cyano, brome, iode ou alkyle, alcoxy ou alcoxycarbonyle alcoxy C¿1?-C¿4? éventuellement substitué dans chaque cas par cyano, halogène ou alcoxy C¿1?-C¿4?, à l'exception du composé N-(2-méthoxy-5-méthyle-phényle)-O[1-(3-trifluorométhylphénoxyméthyle)-propyl]-carbamate. L'invention concerne également des procédés permettant de les préparer et leur utilisation comme herbicides.
