ABSTRACT:

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.
