Title:
METHOD FOR MAKING N-(FLUOROSULFONYL) DIMETHYLAMINE
Document Type and Number:
WIPO Patent Application WO/2018/094233
Kind Code:
A3
Abstract:
Dimethylamine (Me2NH) is reacted with sulfuryl fluoride (S02F2) to form at least a first phase comprising N-(fluorosulfonyl) dimethylamine (FS02NMe2), tetramethylsulfamide (S02(NMe2)2), or a combination thereof. A second phase, which may include dimethylamine hydrofluoride (Me2NH2F), may be also formed and separated from the first phase. FS02NMe2 or S02(NMe2)2 is then isolated from the first phase. For example, the first phase may be a liquid phase, and FS02NMe2 and S02(NMe2)2 are separated by distillation, optionally under reduced pressure.
