| abstract |
The present invention relates to novel compounds of the formula I and the N-oxides, stereoisomers, tautomers and agriculturally or veterinarily acceptable salts thereof 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 one or two non-adjacent bonds in the 5-membered ring formed by C 1 , C 2 , A 1 , A 2 and A 3 are double bonds, while the others are single bonds, provided that the bond between A 1 and A 2 or the bond between A 1 and C 1 or the bond between A2 and A3 or the bond between C 1 and C 2 or the bond between A 3 and C 2 is a double bond further provided that at least one of A 1 , A 2 and A 3 is N, N(R 3 ) or N(R 6 ), and where Ar, R 1 , R 2 , R 3 , R 4 ,R 5 , R 6 , R 7 , R 8 , R 9 and (R) k are as defined in the claims and in the description, which are useful for combating or controlling invertebrate pests, in particular arthropod pests and nematodes. The invention also relates to a method for controlling invertebrate pests by using these compounds and to plant propagation material and to an agricultural and a veterinary composition comprising said compounds. |
