Novel compounds having insecticidal and acaricidal activity which is retained over long periods of time under outdoor conditions have the general formula: <IMAGE> in which: A represents CF3-C IDENTICAL C-, <IMAGE> in which X represents a hydrogen, fluorine, chlorine or bromine atom, and Y represents a chlorine or bromine atom, and R represents <IMAGE> the group <IMAGE> is bound to the 2 or 3 position, <IMAGE> in which R<1> represents a hydrogen atom, -CN or -C IDENTICAL CH, R<2> represents a 3-phenoxy, 3- benzyl, 4-allyl or 4-propargyl group, R<3> represents a hydrogen atom or an alkyl group and is bound to the 2 or 3 position, R<4> represents a benzyl, benzoyl, phenoxy, allyl or propargyl group and is bound to the 4 or 5 position, Z represents an oxygen or sulphur atom, R<5> and R<6> each independently represent an alkyl group having 1 to 3 carbon atoms or R<5> and R<6> together with the atoms to which they are bonded represent an aromatic, heteroaromatic or aliphatic, saturated or unsaturated orthocondensed ring, R<7> and R<8> independently represent a hydrogen or halogen atom or CH3, and R<9> represents a phenyl, vinyl substituted vinyl or phenoxy group. Novel intermediates of formula I wherein R is hydrogen or C1-C4 alkyl are also described. |
