Rate constant ratios, kd/kc, for the disproportionation/combination reaction at a temperature of 295 ± 2 K, have been measured as 0.034 ± 0.009 for the collision between CF3CH2CF2 + CF3 radicals and as 0.075 ± 0.019 for CF3CH2CF2 + CF3CH2CF2 radicals. The effect of the two fluorine substituents on the rate constant ratio is compared to previous kd/kcs with CF3CH2CH2, CF3CH2CHCl, and CF3CH2CHCF3 radicals.

The fluorination of butane over cobalt trifluoride has given a complex mixture of partially fluorinated compounds: 51 of these have been identified, comprising over 99percent of the products.Most were polyfluor-butanes but 1-2percent were polyfluoro-2-methylpropanes.The reaction has no synthetic utility.There was some selectivity in the fluorination: secondary C-H was convertart byed into C-F more easily then primary, and the ease of replacement of a particular H was reduced by geminal vicinal fluorines.A computer model of the fluorination was only partially successful, perhaps because the fluorination proceeded in part by simple F for H replacement and in part via alkenes: the model only allowed for the former.

The reaction of mono- and dibasic 2-oxocarboxylic acids with sulfur tetrafluoride leads to loss of carbon monoxide.The resulting polyfluoroalkane products contain one less carbon atom than the starting oxoacid. 3-Oxopentanedioic and 4-oxopentanoic acids react with SF4 without cleavage of carbon-carbon bonds.Depending on the reaction conditions, the reaction products consist either of polyfluoroalkanes or acyl fluoride derivatives of fluorinated carboxylic acids.
