ResumoIn recent years considerable attention has been directed to hypofluorite chemistry. Fluoroxytrifluoromethane, because of its high thermal stability and the easy preparation methods available, is the model compound to explore the chemistry of the reactive OF bond. Bis(fluoroxy)difluoromethane CF2(OF)2 has been much less studied, even though it has been known since 1967. Its investigation and applications have been inhibited by its tendency to decompose in the presence of hydrocarbon impurities both in the condensed and the gas phase. Pure samples of CF2(OF)2 can decompose violently to CF4 and O2 by initiation at extremely low temperature; however it appears quite unreactive towards some perfluoro-cycloolefins and other reducing agents such as carbon monoxide. The general reactivity of CF2(OF)2 towards halo-olefins, investigated in semicontinuous and continuous techniques, introduces a new and useful method for the preparation of halogenated 2,2-difluoro-1,3-dioxolanes.
