Hexafluoropropylene oxide synthesis

A particularly important process for the synthesis of fluorinated monomers is attack of functionalized perfluoroalkoxides onto hexafluoropropylene oxide [271, 272, 273, 274] (equation 60) or other fluorinated epoxides [275, 276], resulting in ring-opening ol the epoxide and formation of a new perfluoroalkoxide or acid fluoride... 

Hexafluoropropylene oxide is an important intermediate in fluoroorganic synthesis. It is useful in the production of surfactants, perfluoropolyether oils, solvents, perfluorinated alkylvinyl ethers, and other materials. 

In studies for the elaboration of a synthesis of perfluoro-n-propyl vinyl ether32), a synthetic precursor of structure 11 was obtained. The program suggested that this compound, 11, would be accessible from two molecules of hexafluoropropylene oxide 12 (Fig. 20). This appeared to be quite an astonishing reaction as extensive bond reorganizations are necessary to achieve the reaction. A chemist who had to... 

When heated above 170"C hexafluoropropylene oxide (5) is a source of difluorocarbene thus, heating 5 in the presence of an alkene allows the synthesis of fluorinated cyclopropanes under neutral conditions.14 16 The less readily available tetrafluoroethylene oxide (6) is also a precursor of difluorocarbene.17... 

The anionic oligomerisation of hexafluoropropylene oxide or tetrafluoroethylene oxide is an alternative source of the hydrophobic/oleophobic fluorocarbon fragment synthesis [126, 128] ...
