24--135- Optically active substituted 24-diamino-135-triazines as herbicides

摘要

The present invention relates to a method and a novel intermediate for herbicides and these optically active a 2,4-diamino-1,3,5-triazine, of producing the novel substituted of formula (I) relates to him for:; [Formula I]; Wherein; Ar represents an optionally substituted aryl, wherein aryl is phenyl, naphthyl, pyridinyl, pyrimidinyl, furyl, benzofuryl, thienyl and benzothienyl from the group consisting of carbonyl carbocyclic or heterocyclic, monocyclic or can represent a bicyclic, aromatic group substituents are cyano, nitro, carbamoyl, thio carbamoyl, halogen, C ₁ -C ₄ - alkyl, C ₁ -C ₄ - halogenoalkyl, C ₁ -C ₄ - alkoxy, C ₁ -C ₄ - halogenoalkyl alkoxy, C ₁ -C ₄ - alkylthio, C ₁ -C ₄ - halogenoalkyl alkylthio, C ₁ -C ₄ - alkylsulfinyl, C ₁ -C ₄ - halogenoalkyl alkyl sulfinyl, C ₁ -C ₄ - alkylsulfonyl, C ₁ -C ₄ - halogenoalkyl alkylsulfonyl, C ₁ -C ₄ - alkylamino and C ₁ -C ₄ - is selected from the group consisting of alkoxycarbonyl ,; R ¹ denotes an alkyl having 1 to 4 carbon atoms,; R ² is optionally having 1 to 4 carbon atoms hydroxyl-, cyano-, halogen- or C ₁ -C ₄ - alkoxy - represents an optionally substituted alkyl,; R ³ is optionally having from 2 to 4 carbon atoms cyano-, halogen- or C ₁ -C ₄ - alkoxy - represents a substituted alkyl,; Where R ¹ is bonded to the substituent on the carbon atom which is arranged in R form.
