Deaminative fluorination of anilines using potassium hydrogen fluoride and silicon tetrafluoride

Article abstract of DOI:10.1016/0022-1139(96)03406-9

It has been found that the combination of potassium hydrogen fluoride and silicon tetrafluoride works as an efficient fluorinating agent for the deaminative fluorination of anilines. A one-pot diazotization of anilines followed by fluoro-dediazoniation proceeds with this combination of the reagents and t-butyl nitrite to afford fluoroarenes.
