Abstract
The invention provides insecticidally active compounds of formula I: ##STR1## wherein A is selected from oxygen and a group of formula S(O).sub.n, where n represents 0, 1 or 2; W represents one or two substituents selected from halo, alkyl, alkoxy, alkoxyalkyl, haloalkyl and haloalkoxy, or W represents a bidentate group linking adjacent carbon atoms, selected from alkylene and alkylenedioxy; Y represents a substituted aryl group where each substituent is selected from halo, alkyl, aryl, aralkyl, aryloxy and arylamino; Z represents a fluoroalkyl group of up to two carbon atoms; and either X' represents hydrogen and X is selected from hydrogen, halo, hydroxy, alkoxy and acyloxy, or X and X' together represent a second bond between the adjacent carbon atoms. The invention also provides processes and intermediates useful for the preparation of the compounds of formula I, insecticidal compositions comprising the compounds of formula I, and methods of combating and controlling pests therewith.
