PATENT OF INVENTION SYNGENTA Compounds of formula wherein Z1 is an oxygen atom; or a sulfur atom; Z2 is an oxygen atom; or a sulfur atom; R 1 is aryl or heteroaryl, which is unsubstituted or substituted; R2 is hydrogen; or an organic substituent; R3 is hydrogen; or an organic substituent; R4 is hydrogen; or an organic substituent; or R3 and R4 taken together form, with the nitrogen atom to which they are attached, a ring, which is unsubstituted or substituted; R5 is hydrogen; or an unsubstituted or substituted alkyl group; or form, taken together with R8 or with a monovalent substituent attached to that R6 atom, wherein R6 is directly attached to the carbon atom, shown in Formula I, which bears R5, an additional linkage; R6 and R7, taken together, form, with the two carbon atoms, shown in formula I, to which they are attached, a bicyclic ring system, which ring system is carbocyclic or heterocyctic, which ring system is substituted, as shown in formula I, by the four substituents -N (R2) -C (= Z1) -R1, -C (= Z2) -N (R3) -R4, R5 and R8, and which ring system is optionally further substituted; and R8 is hydrogen; or an unsubstituted or substituted alkyl group; or forms, with R5 or with a monovalent substituent attached to that R7 atom, the atom by which R7 is directly attached to the carbon atom, shown in formula I, which bears R8, an additional bond, and, when that is Where appropriate, their tautomers, in each case in free form or in salt form, may be used as agrochemically active ingredients and may be prepared in a manner known per se. |
