Perflucrooctyl-substituted cycloalkanes are prepared directly by photolysis of perfluoroazooctane in cycloalkanes upon 185 nm irradiation; a plausible mechanism is discussed on the basis of the time-course, quantum yield, and light intensity dependence during this photoreaction.

Reaction of RfI (RfC6F13 or C8F17) with Cd powder in DMF at room temperature under N2 afforded RfCdX (XI or Rf) in moderate (48–52%) yield. Although no reaction was observed with Cd powder and RfI (RfC6F13 or C8F17) in CH3CN at room temperature, reaction at reflux gave the homocoupled products C6F13C6F13 (67%) and C8F17C8F17 (61%), respectively. No F-alkylcadmium reagent was detected by 19F NMR

A new synthesis of perfluoroalkylmethyloxiranes and perfluoroalkylmethylaziridines is accomplished by addition of allylalcohol or allylamine to iodoperfluoroalkanes in the presence of potassium or sodium hydroxide.

the other hand ICF2CF2I and C1CF2CFC1I, by a 1,2-dehalogenation reaction, form the olefins CF2 = CF2 and CF2 = CFC1, respectively, as the principal products. The interaction of RfI compounds with cadmium in other solvent media, e.g. diethyl ether. tetrahydrofuran (THF), N,N-dimethylformamide (DMF), and bis(2-methoxyethyl)ether(diglyme) were examined and found to produce a different ratio of RfRf and
