ABSTRACT:
Two kinds of novel fluorobenzophenones represented by the general formula (A), wherein X is F or Cl, are synthesized from 1,2-difluorobenzene and 4,4'-difluorobenzophenone, respectively. Novel fluorophenyl fluorobenzoates represented by the general formula (B), wherein X is F or Cl, are obtained by oxidizing the fluorobenzophenones (A), respectively, in an organic solvent by using trifluoroacetic acid and aqueous solution of hydrogen peroxide. By hydrolysis of each of the fluorobenzoates (B), 3,4-difluorophenol or 3-chloro-4-fluorophenol can easily be obtained. ##STR1##
