  • Process for preparing 3,5-difluoroaniline
    Patent number: 5977412
    Abstract: The invention provides a novel process for producing a 3,5-difluoroaniline compound by reacting a 2-halo-4,6-difluoroaniline with a diazotizing agent in the presence of a reducing agent to form a diazonium salt. Build-up of potentially dangerous diazonium salt is avoided by reducing the diazonium salt with the reducing agent, to form a 1-halo-3,5-difluorobenzene, contemporaneously with the diazotization reaction. The 1-halo-3,5-difluorobenzene is then aminated.
