Chemical compound

Difluoroamine (also calledfluorimide ordifluoramine) is aninorganic compound with the chemical formula NHF2. It consists of anammonia molecule on which two of thehydrogen atoms have beensubstituted byfluorine atoms, and is thus the fluorine analog ofdichloramine.

Synthesis

[edit]

Difluoramine can be made by hydrolisingN,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 oftetrafluorohydrazine andthiophenol.[2]

N2F4 + 2 C6H5SH → 2 NHF2 + C6H5SSC6H5

It is produced in small amounts as a by product whennitrogen trifluoride is reduced byarsenic. Also it is a byproduct in the fluorination ofurea.[3] Small amounts are produced whenammonium hydrogen difluoride is electrolysed.[2]
