| abstract |
The present invention relates to novel compounds of formula I and their N-oxides, stereoisomers, tautomers and agronomically or veterinarily acceptable salts useful in the prevention or control of invertebrate insects, especially arthropod pests and nematodes : 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 ); A 3 is N, O, S, N (R 6 ), C (R 7 ) or C (R 8 , R 9 ); Herein, 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 and the remainder are single bonds, provided that between A 1 and A 2 a bond or a 1 and the bond between the bond between C 1 or a 2, and the bond between the bond or C 1 and C 2 between the a 3 or a 3 and C 2 is a 1, further a double bond, a 2, and A 3 is N, N (R 3 ) or N (R 6 ), 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 specification. The present invention also relates to methods of controlling invertebrate pests using such compounds and to plant propagation material comprising such compounds, and to agricultural and veterinary compositions. |
