Heterocyclische Amidderivate und ihre Verwendung als Schädlingsbekämpfungsmittel

Compounds having pesticidal activity of formula (I> Q(CH2)n(O)bQ1CR2=CR3CR4=CR5CX1NHR1 or one of its salts, in which Q is a monocyclic ring system or a system containing an optionally substituted condensed bicyclic ring in which at least one ring is aromatic or Q is a dihalovinyl group or a group R6C IDENTICAL C-, in which R6 is C1-4 alkyl, tri(C1-4 alkyl)silyl, halogen or hydrogen; Q1 is a 1,2-cyclopropyl ring, optionally substituted by one or a number of groups chosen from C1-3 alkyl, halogen, C1-3 haloalkyl, C1-3 alkynyl or cyano; or Q1 is (CH2)m, in which m = 1 to 7; a = 0 or 1; b = 0 or 1; R2, R3, R4 and R5 are identical or different, at least one of them being hydrogen and the others being chosen independently from hydrogen, halogen, C1-4 alkyl or C1-4 haloalkyl; X1 is oxygen or sulphur; R1 is a five or six-membered, heteroaromatic or partially saturated ring system containing a minimum of one and up to four heteroatoms chosen individually from nitrogen, sulphur and oxygen, or R1 is a five- or six-membered saturated ring system containing one or a number of heteroatoms chosen individually from nitrogen, oxygen and sulphur; are described as well as their processes of preparation, intermediates used in their preparation, the pesticidal compositions which contain them and their use against parasites.
