Abstract
The invention relates to novel substituted thienyl(amino)sulphonylureas of the general formula (I) in which A, Q, R1, R2, R3, R4 and R5 are each as defined in the description, to processes for their preparation and to their use as herbicides.
Claims7
A compound of the Formula (I)
- wherein
- A represents nitrogen,
- Q represents a single bond or represents NH,
- R1 represents hydrogen, represents halogen, represents in each case optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 4 carbon atoms in the alkyl groups, or represents in each case optionally cyano-, halogen-, C1-C4-alkyl- or C1-C4-alkoxy-substituted phenoxy, oxetanyloxy, furyloxy or tetrahydrofuryloxy,
- R2 represents hydrogen, represents halogen, represents in each case optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 4 carbon atoms in the alkyl groups, represents in each case optionally cyano-, halogen-, C1-C4-alkyl- or C1-C4-alkoxy-substituted phenoxy, oxetanyloxy, furyloxy or tetrahydrofuryloxy,
- R3 represents hydrogen or represents optionally C1-C4-alkoxy-, C1-C4-alkyl-carbonyl- or C1-C4-alkoxy-carbonyl-substituted alkyl having 1 to 4 carbon atoms,
- R4 represents optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl having 1 to 6 carbon atoms and—if Q represents NH— also represents hydroagen, and
- R5 represents hydrogen, represents optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl having 1 to 6 carbon atoms, represents in each case optionally halogen-substituted alkenyl or alkinyl having in each case 2 to 6 carbon atoms, represents in each case optionally cyano-, halogen- or C1-C4-alkyl-substituted cycloalkyl or cycoalkylalkyl having in each case 3 to 6 carbon atoms in the cycloalkyl groups and optionally 1 to 4 carbon atoms in the alkyl moiety, or represents in each case optionally cyano-, halogen-, C1-C4-alkyl- or C1-C4-alkoxy-substituted oxetanyl, furyl or tetrahydrofuryl and a salt of the compound of the Formula (I).
