Dimethylamine (Me
2
NH) is reacted with sulfuryl fluoride (SO
2
F
2
) to form at least a first phase comprising N-(fluoro sulfonyl) dimethylamine (FSO
2
NMe
2
), tetramethylsulfamide (SO
2
(NMe
2
)
2
), or a combination thereof. A second phase, which may include dimethylamine hydrofluoride (Me
2
NH
2
F), may be also formed and separated from the first phase. FSO
2
NMe
2
or SO
2
(NMe
2
)
2
is then isolated from the first phase. For example, the first phase may be a liquid phase, and FSO
2
NMe
2
and SO
2
(NMe
2
)
2
are separated by distillation, optionally under reduced pressure.
