Difluoroamine is used as a reagent for introducing difluoroamine groups into organic molecules; synthesis of diazirines; deamination of primary amines. | [Preparation]
Difluoramine can be generated from tetrafluorohydrazine, which is made by reaction
of NF3 with various metals at 375 °C.[1] Conversion into difluoramine is accomplished by heating
tetrafluorohydrazine with Thiophenol in an evacuated bulb.[2] Difluoramine is also generated by heating N,N-difluorourea with conc. Sulfuric Acid.[3] | [storage]
Difluoroamine is shock sensitive. Reactions should be carried out in a fume hood.
