Descrizione generale

Reaction between chloropentafluorobenzene and strong N-bases in polar aprotic solvents and in the presence of water has been investigated. Chloropentafluorobenzene on reaction with ammonia yields 4-chloro-2,3,5,6-tetrafluoroaniline and 2-chloro-3,4,5,6-tetrafluoroaniline.

Applicazioni

Chloropentafluorobenzene has been used in the preparation of:
  • 1,2-difluoro-1,2-bis-(pentafluorophenyl)dichlorane via fluorination with elemental fluorine at 128°C
  • 5-chloro-1-(difluorochloro)-2,3,4,5,6,6-hexafluoro-1,3-cyclohexadiene via reaction with chlorine trifluoride at −78°C
