Insecticides. The present invention relates to compounds of formula (I) wherein Z 1 is an oxygen atom; or a sulfur atom; Z ~ 2 ~ is an oxygen atom; or a sulfur atom; R1 is an aryl or heteroaryl group which is unsubstituted or substituted; R 2 is hydrogen; or an organic substituent; R3 is hydrogen; or an organic substituent: R4 is hydrogen; or an organic substituent; or R3 and R4 when together form, together 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, when together with R 8 or a monovalent substituent attached to that R 6 atom, whereby the R 6 atom is directly connected with the carbon atom shown in formula I, which carries R ~ 5 ~ an additional bond; R 6 and R 7 when together form together with the two carbon atoms shown in formula I, which atoms they are attached to is a bicyclic ring system which is carbocyclic or heterocyclic ring system which is substituted, in the manner shown in formula I, by the four substituents -N (R 2 ~) -C (= Z ~ 1 ~, -R ~ 1 ~, -C (= Z ~ 2 ~) - N (R3) -R4-, R5- and R8- and the ring system which is optionally further substituted and R8- is hydrogen, or an unsubstituted or substituted alkyl group; or form, when together with R 5 ~ or a monovalent substituent attached to that R 7 atom, whereby the R 7 atom is directly attached to the carbon atom shown in formula I, which carries An additional bond, and, where appropriate, tautomers thereof, in each case in free or salt form, may be used as active agrochemical ingredients and may be prepared in a manner known per se. |
