A compound of formula (I):P-R2-Q(I)where each of P and Q is, independently, a group of formula (B): wherein J is a bidentate group of formula -CH2-X-CH2- (wherein X is methylene, sulfur or oxygen), X'C=CY or X'WC-CYZ (wherein X', W, Y and Z are independently hydrogen, hydroxy, acyloxy, alkoxy, alkylsilyloxy or halogen); R1 is an optionally substituted phenyl or 5-or 6-membered heterocyclic ring system containing from 1 to 3 heteroatoms individually selected from nitrogen, oxygen and sulfur atoms, and at least one unsaturation (double bond) between adjacent atoms in the ring, said heterocyclic ring being optionally fused to a benzene ring, wherein the substutuents, if present, are selected from halogen atoms, cyano, alkyl, alkenyl, alkynyl, alkoxy, haloalkyl, haloalkenyl, alkylthio and alkyl amino groups, any of which groups contain up to six carbon atoms; R2 is a bidentate linking group and is a substituted or unsubstituted alkylene, alkylenearyl, alkyleneheteroaryl, alkenylene, alkylenylarylalkylenyl, carbonyl or diacyl group, provided that when R2 is alkenylene or alkylenylarylalkylenyl said group does not have an unsaturated carbon atom bonding directly to the ring nitrogen of formula (B); R3 is hydrogen, cyano, hydroxy, alkyl, alkoxy, amino, nitro, isocyanato, acylamino, hydroxyalkyl, optionally substituted heteroaryl, alkoxyalkyl, haloalkyl, halohydroxyalkyl, aralkyloxyalkyl, acyloxyalkyl, amidoximido, sulfonyloxyalkyl, aminoalkyl, alkoxycarbonylamino, acylaminoalkyl, cyanoalkyl, imino, formyl, acyl or carboxylic acid or an ester or amide thereof, or alkenyl or alkynyl either of which is optionally substituted by halogen, alkoxy, cycloalkyl, optionally substituted aryl, optionally substituted heteroaryl or cyano; or an acid addition salt, quaternary ammonium salt or +E,uns N+EE -oxide derived therefrom; an insecticidal, acaricidal or nematicidal composition comprising (I). |
