The fluorides KF, RbF and CsF have been known to serve as catalysts for the reaction, CF2O F2 yielding CF3OF. The list of catalysts for this process has now been enlarged to include NaF, MgF2, CaF2, SrF2, BaF2 and LaF3. Silver fluoride, usually a mixture of AgF2 with AgF, has been known to catalyze the reaction of CF2O with F2 to give both CF3OF and CF3OOCF3. It has now been shown that TlF3 behaves like silver fluoride. It has also been shown that many other fluorides of metals give higher yields of CF3OOCF3 than of CF3OF but require higher temperatures. Various possible mechanisms for these catalytic processes are discussed. Author
