Fluorosulphates of most of the lanthanide elements in the oxidation state iii have been prepared by the action of peroxydisulphuryl difluoride on the anhydrous metal carbonates. The oxides of neodymium, samarium, and europium, however, gave indications of partial reaction with S2O6F2 to form mixtures of fluorosulphate with oxide. The vibrational spectra and structure of the lanthanide fluorosulphates suggested the presence of mixed co-ordination type anions. Fluorescence emission, and vibrational spectra of the europium compound indicated octaco-ordination and the presence of ter- and bi-dentate fluorosulphate groups.

Oxygen difluoride is a strong oxiding agent. When mixed with hydrogen, carbon monoxide, methane or carbon, and ignited with an electrical shock, the mixture explodes forming various products. It catches fire in contact with nitric oxide. 

As a rule xenon difluoride does not react with alkanes. Methane is oxidized by a water solution of xenon difluoride under high pressure (3.8 x 104"— 15.2 x 104 Torr) at 10-25 C in a special high-pressure reactor to form a mixture of methanol (4-8%), fluoromethane (1-2%) and carbon dioxide (25-50%).12...

The reaction starts undoubtedly by opening of the lactone ring by cesium fluoride to form cesium salt of 4-hydroxyperfluorobutyryl fluoride. The anion of this intermediate opens the ring of perfluoropropylene oxide at the central carbon. Expulsion of fluoride anion from the terminal difluoro-methylene group converts the intermediate to the difluoride of perfluoro-... 

Oxygen difluoride reacts rapidly with selected alkenes at low temperatures however, per-fliioroalkenes are less reactive than the corresponding alkylalkenes and require either thermal or ultraviolet activation." The oxidation, which is a homogeneous chain reaction," of hexa-fluoropropene, tetrafluorocyclopropene, and pcrfluorobut-2-ene all give a variety of products such as carbon tetrafluoridc, carbonyl difluoride, hexafluoroethane, oxiranes, and other oxidation products." This reaction is not useful for preparative organic work. 

The fluorination of adamantane and its derivatives can also be achieved with oxygen difluoride in the presence of sodium hydrogen carbonate as a hydrogen fluoride trap however, this reaction is complicated by competing oxidation.22 When the fluorination of adamantane is performed with cesium fluoroxysulfate, a mixture of monofluorinated products 4 and 5 arising from fluorination at tertiary and secondary sites, respectively, and difluorinated product 6 is obtained.23 The thermally initiated fluorination of adamantane using xenon difluoride gives a similar mixture but includes a small amount of trifluoride 7.24 25... 

The electrochemical properties of the prepared materials were evaluated using coin-t e cells. The positive electrode consisted of 80 wt% oxide powder, 10 wt% carbon, and 10 wt% poljwinylidene difluoride (PVDF) binder on aluminum foil. The negative electrode was either metallic lithium or carbon on copper foil. The electroljde was 1 M LiPFe in a 1 1 mixture of ethylene carbonate (EC)/diethyl carbonate (DEC). The coin cells were galvanostatically cycled at 2.8 4.3 V. The a.c. impedance of the cointype cells was measured in the frequency range of lOmHz-lOOKHz using an impedance analyzer (BAS-ZAHNERIM6). 

Carbonyl difluoride will react with partially oxidized charcoals to produce graphite fluorides, containing up to 10% fluoride [ICI29]. Treatment of carbonyl difluoride with carbon monoxide at temperatures in excess of 350 C and elevated pressures, and in the presence of a catalyst e.g. Fe or CuFj), is reported to generate tetrafluoroethene [842] ... 

The fiuorosulphates of scandium, yttrium, and most of the lanthanide elements in the oxidation state m have been prepared by the action of peroxydisulphuryl difluoride on the anhydrous carbonates of the metals. ...
