Page/Page column 14/21, (2009/08/14)
The invention pertains to a process for preparing compounds of formula (I-A) or (I-B) here below: by reaction of perfluoroallylfluorosulfate (FAFS) of formula (II): with at least one hypofluorite of formula (II-A) or (II-B): wherein: RF in formulae (I-A) and (II-A) is a monovalent fluorocarbon C1-C20 group, optionally comprising oxygen catenary atoms, optionally comprising functional groups comprising heteroatoms (e.g. -SO2F groups); R'F in formulae (I-B) and (II-B) is a divalent fluorocarbon C-1-C6 group, preferably a group of formula (III): wherein X1 and X2, equal to or different from each other, are independently a fluorine atom or a C1-C3 fluorocarbon group. The FAFS-hypofluohte adducts of formulae (I-A) and (I-B) can be produced with high selectivity so as to access useful intermediates which can further be reacted taking advantage of the un-modified fluorosulfate group chemistry.

The present application provides a process to produce fluorinated vinyl ether by reacting a 2-alkoxypropionyl fluoride with a metal carbonate under anhydrous conditions in a stirred bed reactor at a temperature above the decarboxylation temperature of an intermediate carboxylate to produce a fluorinated vinyl ether. The process is carried out in the absence of solvent. With the process described, fluorinated vinyl ether of a high purity can be obtained in a high throughput manner.
