CF3CFzCFz CFsNFz. NF2 and the final production of n-CkFgNF2. On the other hand, the original adduct might undergo cleavage with the formation of FCN and CF3CF2CF= N.. The latter would then undergo alkylation by CFzN= N. itself produced by the fluorination of FCN through the nitrene and azo dimer. 3 This would give first the isolated unsaturate CF3N= CFC? F~ and finally its saturated analog. Similar schemes may readily be set up for the ...
