Paragraph 0020; 0021; 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.

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

Direct hydroperfluoralkylation of electron-deficient alkenes - ethyl acrylates 4, 7, and 8, acrylonitrile (5), and methyl vinyl ketone (6) - with perfluoroalkyl halides RfX (1, X = I; 2, X = Br) in the presence of cobaloxime(III) (3) and zinc gives 1:1 hydroperfluoroalkylation adducts in good yields.This reaction provides a convenient synthesis of β-(perfluoroalkyl)carboxylic esters 9, 12, and 13, nitriles 10, and ketones 11.Details of the reaction including effect of solvent, temperature, and ratio of reagents were examined.The reaction is proposed to proceed via a radical mechanism initiated by low-valent cobalt.
