Difluoramine
Chemical compound
From Wikipedia, the free encyclopedia
Difluoroamine (also called fluorimide or difluoramine) is an inorganic compound with the chemical formula NHF2. It consists of an ammonia molecule on which two of the hydrogen atoms have been substituted by fluorine atoms, and is thus the fluorine analog of dichloramine.

Synthesis
Difluoramine can be made by hydrolising N,N-difluorourea.[1]
- CH4N2O + 2 F2 → CH2F2N2O + 2 HF
- CH2F2N2O + 2 HF + H2O → HNF2 + CO2 + NH4F•HF
It may also be produced in the reaction of tetrafluorohydrazine and thiophenol.[2]
- N2F4 + 2 C6H5SH → 2 NHF2 + C6H5SSC6H5
It is produced in small amounts as a by product when nitrogen trifluoride is reduced by arsenic. Also it is a byproduct in the fluorination of urea.[3] Small amounts are produced when ammonium hydrogen difluoride is electrolysed.[2]
