The Generation of CF and an Investigation of the Products of Its Reaction with Alkenes

Article abstract of DOI:10.1021/ja00280a029

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.
