<p>Compounds of Formula (I): <CHEM> wherein: Ar is phenyl, naphthyl, thienyl, fluorenyl, phenanthrenyl, dibenzo furanyl or a polynuclear group (A); <CHEM> in which a is 0, 1 or 2; B is (D)b(CH2)c(E)ewhere each of D and E is oxygen or sulphur, b and e are independently 0 or 1 but not both 1, and c is 0, 1, 2 or 3, the sum of a,b,c and e being at least 3, and the ring containing B is wholly or partially saturated; and G is hydrogen or a benzene ring fused to the benzene ring of group (A); any of the groups Ar may be substituted by one or more of C1-4 alkyl, halo-(C1-4) alkyl, halo, C1-4 alkoxy (except 3,4-methylenedioxy) or C1-4 halo -alkoxy; n is 1 to 8, except that n is 1 to 4 when Ar is phenyl or substituted phenyl; each of R<2> and R<3> is in each case independently hydrogen, C1-4 alkyl or halo-(C1-4) alkyl; and R and R<1> are each selected from hydrogen, alkyl, cycloalkyl, alkenyl or alkoxy (any of which may be substituted by halo, alkenyl, alkyl, cycloalkyl, alkoxy, alkynyl or cyano) are insecticidal and acaricidal. ></p> |
