| abstract |
The present invention relates to novel compounds of the formula I and their N-oxides, stereoisomers, tautomers and agriculturally or veterinarily usable compounds which can be used for controlling or controlling invertebrate pests, especially arthropods and nematodes Salt, wherein C 1 is C or CH; C 2 is C or CH; A 1 is N or C; A 2 is N, C(R 2 ), N(R 3 ), O, S or C(R 4 , R 5 ); and A 3 is N, O, S, N(R 6 ), C(R 7 ) or C(R 8 , R 9 ); where C 1 , C 2 , A 1 , A 2 and One or two non-adjacent bonds in the 5 - membered ring formed by A3 are double bonds and the others are single bonds, provided that the bond between A1 and A2 or the bond between A1 and C1 or A The bond between 2 and A 3 or the bond between C 1 and C 2 or the bond between A 3 and C 2 is a double bond, with the further condition that at least one of A 1 , A 2 and A 3 is N, N(R 3 ) or N(R 6 ), and wherein Ar, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and (R) k are as claimed in the claims and as defined in the specification. The invention also relates to a method for controlling invertebrate pests by using these compounds as well as plant propagation material and agricultural and veterinary compositions comprising said compounds. |
