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.
