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.
二甲胺(Me2NH)与亚磺酰氟(SO2F2)反应,形成至少包括N-(氟磺酰基)二甲胺(FSO2NMe2)、四甲基磺酰胺(SO2(NMe2)2)或两者的第一阶段。第二阶段可能包括二甲胺氢氟化物(Me2NH2F),也可以形成并与第一阶段分离。然后从第一阶段中分离出FSO2NMe2或SO2(NMe2)2。例如,第一阶段可以是液相,FSO2NMe2和SO2(NMe2)2可以通过蒸馏分离,可选择在减压下进行。
