KINETIC STUDY OF CHEMICALLY ACTIVATED FLUOROCYCLOPROPANE.
Dall'O,Heydtmann
, p. 24 - 30 (2007/10/02)
The photolysis of ketene at 313 nm was studied in the presence of fluoroethene and oxygen. The product formation was observed as a function of total pressure between 12 and 1080 mbar. Chemically activated fluorocyclopropane was formed by addition of singlet methylene to the double bond, and subsequent isomerization to the fluoropropenes as well as decomposition of these primary products to allene, propyne and HF was observed. The product yield was described by RRKM calculations; a stepladder deactivation model was used.

The reaction of arc generated carbon atoms with CF4 at 77 K in the presence of alkene trapping agents results in the formation of fluorocyclopropanes and 1,1-difluoroalkanes.The fluorocyclopropanes are postulated to arise by addition of CF to the double bond generating a cyclopropyl radical which abstracts H.CF adds stereospecifically to olefins and gives both cis and trans fluorocyclopropanes with the trans generally predominating.The 1,1-difluoroalkanes are postulated to be the result of a 3CF2 reaction.In the presence of oxygen, the CF is oxidized to CO2, and the 3CF2 gives carbonyl fluoride.
