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]
