| abstract |
The present invention relates to N-acylimino compound of formula (I): wherein X is O or S, in particular O; Y is a single bond, O, S or NR 5 ; Het is a 5 or 6 membered carbon-bound or nitrogen-bound heterocyclic ring, W 1 -W 2 -W 3 -W 4 represents a carbon chain group connected to N and C=N, and thus forming a saturated, unsaturated, or partially unsaturated 5 or 6 membered nitrogen containing heterocycle, wherein W 1 , W 2 , W 3 and W 4 each individually represent CR v VR w ; R1, may be hydrogen, halogen, etc.; R3 may be hydrogen, CN, C 1 -C 6 -alkyl, etc.; R4 may be of hydrogen, C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, C 2 -C 6 -alkinyl, C 3 -C 8 -cycloalkyl, Q- phenyl, Q'-O-phenyl, Q'-S-phenyl, where the phenyl ring is optionally substituted with one or more, e.g. 1, 2, 3, 4 or 5 identical or different substituents R 10 , and the moieties Q-Het # , Q'-0-Het # and Q'-S-Het # where Het# represents a heterocyclic rad- ical and where Q and Q' are C 1 -C 6 -alkandiyl, C 2 -C 6 -alkendiyl, or C 2 -C 6 -alkyndiyl, and where Q may also be a single bond; R 3 and R 4 together may also may also a bivalent radical, selected from the group consisting of C 2 -C 5 -alkandiyl, C 2 -C 5 -alkendiyl, Q"-C 1 -C 4 -alkandiyl and Q"-C 2 -C 4 -alkendiyl, where Q" is O or S. The invention also relates to the use of the N-acylimino heterocyclic compounds, their stereoisomers, their tautomers and their salts, for combating invertebrate pests. Furthermore the invention relates also to methods of combating invertebrate pests, which comprises applying such compounds. |
