Abstract
Compounds of formula (I) are prepared by hydrogenolysis of a compound of formula (II): where R1 is haloalkyl, haloalkoxy or −SF5; W is N or CR3; and R2 and R3 are H or Cl. The compounds of formula (I) can be used as intermediates in the preparation of pesticidally active arylpyrazole compounds.
