Heterocyclic fluoroalkenyl thioethers (II)

The present invention relates to novel heterocyclic fluoroalkenyl thioethers of the formula (I) ##STR1##

in which

X represents hydrogen, halogen or alkyl,

m represents integers from 3 to 10,

n represents 0, 1 or 2,

Het represents the groups ##STR2##

where

• R¹ represents hydrogen; mercapto; optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl or alkenyl; optionally substituted aryl; or optionally substituted heterocyclyl,
• Y represents oxygen or sulphur, and
• R² represents hydrogen, alkyl or optionally substituted aryl,

  and to processes for their preparation and to their use as pesticides.
