Reactions of organic hypofluorites

In an attempt to prepare trifluoromethanoi, CF3OH, trifluoromethyl hypofluorite was treated with an equal flow rate of dihydrogen at about 160 C in a reaction vessel packed with copper ribbon [1078e]. However, the reaction proceeded to give carbonyl difluoride in accordance with  

Trifluoromethyl hypofluorite reacts with mercury at room temperature to afford COFj and HgjFj [1648]. Lithium reacts similarly, but more slowly at the same temperature, giving COFj and lithium fluoride. With sulfur, both COFj and SF are produced according to the stoicheiometry [1648]  

In the presence of an equimolar amount of methane, CFjCFjOF is almost completely decomposed in 24 h [1653b]. The mechanism for the propagation of this reaction is believed to occur as follows  

In the presence of mercury, CFgCFjOF forms CF3C(0)F, carbonyl difluoride and tetrafluoromethane [1653b]. 

Thermal decomposition of CF 3CF CF OF behaves in a similar way to that for CF3CF2OF, with cleavage occurring at the C-C bond adjacent to the OF group, to give
