Volume: 125 Issue: 2 Pages: 189-197

In the present work we give an overview of the CF2(OF)(2) radical reactivity and report the synthesis of new perfluorovinylethers. CF2=CF-OCF2OCF2CF3 and CF2=CF-OCF2OCF2CF2OCF3 are prepared in a semi-continuous methodology starting from CF2(OF)(2). These highly reactive vinylethers are characterized by the OCF2O group directly bonded to the insaturation. For this reason they are excellent candidates for the preparation of very low T-g perfluororubbers.

Organic hypofluorites and their new role in industrial fluorine chemistry

Author(s): Navarrini, W; Tortelli, V; Russo, A; Corti, S.


Volume: 95 Issue: 1-2 Pages: 27-39

DOI: 10.1016/S0022-1139(98)00296-6 Published: JUN 4 1999


In this work a historical background of the synthesis and chemistry of fluorinated organic hypofluorites is given and some of the known applications of this class of compounds are reviewed. Recently, new industrial processes based on hypofluorite chemistry have been developed for the production of a variety of fluoromonomers. These processes are all based on the addition of hypofluorites having different structures to fluorinated olefins. Some mechanistic features of this key reaction are discussed, in terms of reactivity and stability of the intermediate primary radicals deriving from homolytic cleavage of the hypofluorite bond. Various aspects of these new processes are described and, in the light of these recent achievements, it is shown how hypofluorite chemistry has acquired great importance as a powerful and versatile methodology for the production of fluoromonomers of prominent industrial interest.
