1H-Perfluoroalkanes are prepared by sodium methoxide reduction of 1-iodoperfluoroalkanes.The experimental evidence indicates that the reaction proceeds either through a radical or a thermal mechanism.We have found that a high yield of 1H-perfluoroalkanes at complete conversion can be accomplished at atmospheric pressure using technology. - Keywords: 1H-Perfluoroalkanes; Methyl hypoiodide; Reduction; Mass spectrometry
Absolute rate constants for some reactions of perfluoro-n-alkyl radicals in solution
Avila, David V.,Ingold,Lusztyk, Janusz,Doibier Jr.,Pan,Muir
, p. 99 - 104 (1994)
Absolute rate constants have been measured at 298 ± 2 K for some reactions of C2F5·, n-C3F7·, n-C7F15·, and n-C8F17· by time- resolved (laser flash photolysis) and competition kinetics. The last three of these radicals exhibit essentially equal reactivities, but C2F5· is somewhat more reactive. The strongly electrophilic nature of these radicals is illustrated by an outstanding Hammett correlation for the addition of n- C8F17· to four para-substituted styrenes, log(k(add)/(X)/k(add)/(H)) = - 0.53σ, (r) = 0.99 (X = p-CH3O to p-CF3), and, far more significantly, by a respectable correlation, (r) = 0.97, of log k(add) with the ionization potentials (IP) of 13 terminal olefins, the values of k(add) for n-C3F7· ranging from 1.6 x 106 to 2.2 x 106 M-1 s-1 for CH2=CHCN (IP = 10.91 eV) to 7.9 x 107 to 8.9 x 107 M-1 s-1 for α-methylstyrene (IP = 8.19 eV). The n-C8F17· radical is 100 times as reactive in hydrogen atom abstraction from tri-n-butyltin hydride as an n-alkyl radical, with k(abs)/(H) (n-C7F15·) = 2.0 x 108 M-1 s-1.
REACTIVITE COMPAREE DES PERFLUOROIODOALCANES (RFI) ET DES PERFLUOROALCOYL-2 IODO-1 ETHANES (RFCH2CH2I) EN PRESENCE DE COUPLE METALLIQUE ZINC-CUIVRE DANS UN SOLVANT DISSOCIANT PARTICULIER : LE SULFOLANE (RF = CnF2n+1, n pair)

, p. 47 - 56 (1983)
Reactivity of perfluoroalkyl iodides (RFI) and perfluoroalkyl-2 iodide-1 ethanes (RFCH2CH2I), in the presence of a zinc-copper couple, in a particular dissociating solvent, "the sulfolane", is described.RFI and RFCH2CH2I react via an organometallic route to give perfluoroorganozinc compounds.Then, RFCH2CH2I react with the sulfolane solvent.In this case, a diperfluoroalkyl-2 ethyl-1 sulfone (RFCH2CH2)2SO2 is obtained.

Paragraph 0016; 0017; 0024, (2019/05/08)
The invention relates to a synthesis method of straight-chain perfluoroalkanes, which comprises the following steps: reaction of perfluoroalkyl iodine with alcohol solution of sodium alcohol at a certain temperature to purify 1-hydroperfluoroalkanes; reaction of 1-hydroperfluoroalkanes with fluorine gas at a certain temperature to purify straight-chain perfluoroalkanes. The synthesis method of theinvention has mild reaction conditions, high product yield, and is beneficial to cost saving. The process has low energy consumption, easy operation and is conducive to industrial production.

, p. 361 - 364 (2007/10/03)
A new and easy way to synthesize acetylene compounds is proposed. This synthesis is improved by including in one-pot, three reactions in a single step, with good yields. The reactants are commonly used compounds.

Rubio,Blancou,Commeyras
, p. 171 - 175 (2007/10/03)
The reactions of perfluoroalkyl iodides with allylbromide or chloride, in the presence of solid potassium hydroxide KOH give 3-perfluoroalkylprop-1-enes RFCH2CH=CH2 in good yields under mild conditions. This reaction represents a synthetically viable and convenient route to such compounds.
