Patent

CA 2267936

The invention relates to a novel substituted 2,4-diamino-1,3,5-triazine of the general formula (I), in which R1 stands for hydrogen or for optionally substituting alkyl, R2 stands for formyl or for optionally substituting alkylcarbonyl, alkoxycarbonyl, alkylsulfonyl, arylcarbonyl or arysulfonyl respectively, R3 for optionally substituting alkyl or cycloalkyl respectively, R4 for hydrogen or alkyl, A for oxygen or methylene, Ar for optionally substituting aryl or heterocyclyl respectively and Z for hydrogen, hydroxy, cyano, nitro, halogen or for optionally substituted alkyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, alkylthio, alkylsulfinyl, alkylsulfonyl, alkenyl or alkinyl respectively (in which three previously known combinations are excluded). The disclosure also relates to a method and to new intermediate products for producing the new compounds and their use as herbicides.

L'invention concerne de nouvelles 2,4-diamino-1,3,5-triazines de la formule générale (I) où R?1¿ représente hydrogène ou bien alkyle éventuellement substitué, R?2¿ représente formyle ou alkylcarbonyle, alcoxycarbonyle, alkylsulfonyle, arylcarbonyle ou arylsulfonyle respectivement éventuellement substitués, R?3¿ représente alkyle ou cycloalkyle respectivement éventuellement substitués, R?4¿ représente hydrogène ou alkyle, A représente oxygène ou méthylène, Ar représente aryle ou hétérocyclyle respectivement éventuellement substitués et Z représente oxygène, hydroxy, cyano, nitro, halogène ou bien alkyle, alcoxy, alkylcarbonyle, alcoxycarbonyle, alkylthio, alkylsulfinyle, alkylsulfonyle, alcényle ou alcynyle respectivement éventuellement substitués (trois composés déjà connus étant exclus). L'invention concerne également un procédé et de nouveaux produits intermédiaires pour la production de nouveaux composés et leur utilisation comme herbicides.
