N-ACYLIMINO HETEROCYCLIC COMPOUNDS

摘要

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 NR5; Het is a 5 or 6 membered carbon-bound or nitrogen-bound heterocyclic ring, W1-W2-W3-W4 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 W1, W2, W3 and W4 each individually represent CRvVRw; R1, may be hydrogen, halogen, etc.; R3 may be hydrogen, CN, C1-C6-alkyl, etc.; R4 may be of hydrogen, C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkinyl, C3-C8-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 R10, 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 C1-C6-alkandiyl, C2-C6-alkendiyl, or C2-C6-alkyndiyl, and where Q may also be a single bond; R3 and R4 together may also may also a bivalent radical, selected from the group consisting of C2-C5-alkandiyl, C2-C5-alkendiyl, Q"-C1-C4-alkandiyl and Q"-C2-C4-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.
