CO2 laser-induced homogeneous decomposition of i-C3F7I yields a variety of perfluorinated compounds, which are suggested to be formed by recombinations of carbenes and radicals generated upon the cleavage of the C-I bond and the fragmentation of the i-C3F7. radical. The decomposition of i-C3F7I in the presence of ethene leads mainly to the formation of (i-3F7CH2)2 and i-C3F7(CH2)2I.
