Novel pyrrole derivatives of the formula <IMAGE> I wherein one of R2 and R3 is <IMAGE> and the other of R2 and R3 as well as R4 and R5 are individually selected from the group consisting of hydrogen, halogen, alkyl of 1 to 18 carbon atoms, aryl of 6 to 14 carbon atoms, aralkyl of 7 to 18 carbon atoms, -CN, -CF3, -NO2, -COOAlk and Alk is alkyl of 1 to 8 carbon atoms, alkoxy of 1 to 8 carbon atoms, <IMAGE> n is 0, 1 or 2, R', R1' and R2' are alkyl of 1 to 8 carbon atoms and R4 and R5 taken together with the carbon atoms to which they are attached may form an optionally further unsaturated carbon homocycle of up to 8 carbon atoms, Z is selected from the group consisting of hydrogen, -CN, -C 3BOND CH, -CF3 and alkyl of 1 to 3 carbon atoms, A is the residue of a pyrethrinoid acid, R1 is selected from the group consisting of <IMAGE> +TR <IMAGE> X', X, Y, Y' and Y'' are individually selected from the group consisting of hydrogen, halogen, alkyl of 1 to 8 carbon atoms and aryl of 6 to 14 carbon atoms, the dotted line indicating an optional double bond, r' is selected from the group consisting of hydrogen, alkyl of 1 to 18 carbon atoms, aryl of 6 to 14 carbon atoms, aralkyl of 7 to 18 carbon atoms, -CF3, -COOAlk and alkoxy of 1 to 8 carbon atoms and Alk has the above definition, R'' and R''' are individually selected from the group consisting of hydrogen, alkyl of 1 to 8 carbon atoms, aryl of 6 to 14 carbon atoms, aralkyl of 6 to 18 carbon atoms, -CF3, -COOAlk' and alkoxy of 1 to 8 carbon atoms and Alk' is alkyl of 1 to 8 carbon atoms having pesticidal properties and novel intermediates. |
