The present invention relates to compounds of formula (I), wherein R, R, R, Rand Rare as defined in claim; or a salt or N-oxide thereof. Furthermore, the present invention relates to processes for preparing compounds of formula (I), to intermediates used in the preparation of compounds of formula (I), to methods of controlling plants and compositions comprising compounds of formula (I). 

Herbicidal compounds

Compounds of the formula (I) in which Z, is an oxygen atom; or a sulfur atom; Zis an oxygen atom; or a sulfur atom; R, is an aryl or heteroaryl group, which is unsubstituted or substituted; Ris hydrogen; or an organic substituent; Ris hydrogen; or an organic substituent; Ris hydrogen; or an organic substituent; or Rand R, taken together, form, together with the nitrogen atom, to which they are attached, a ring, which is unsubstituted or substituted; Ris hydrogen; or an unsubstituted or substituted alkyl group; or forms, taken together with Ror with a monovalent substituent attached to that atom of R, via which atom Ris directly connected with the carbon atom, shown in the formula I, which carries R, one additional bond; Rand R, taken together, form, together with the two carbon atoms, shown in the formula I, to which atoms they are attached, a bicyclic ring system, which ring system is carbocyclic or heterocyclic, which ring system is substituted, in the manner shown in the formula I, by the four substituents &#x2014;N(R2)-C(&#x2550;Z1)-R, &#x2014;C(&#x2550;Z2)-N(R3)-R4, Rand R8, and which ring system is optionally further substituted; and Ris hydrogen; or an unsubstituted or substituted alkyl group; or forms, taken together with Ror with a monovalent substituent attached to that atom of R, via which atom Ris directly connected with the carbon atom, shown in the formula I, which carries R8, one additional bond, and, where appropriate, tautomers thereof, in each case in free form or in salt form, can be used as agrochemical active ingredients and can be prepared in a manner known per se.
