Novel fluorinated amphiphilic cyclodextrin derivatives: Synthesis of mono-, di- and heptakis-(6-deoxy-6-perfluoroalkylthio)-β-cyclodextrins
Peroche, Sandrine,Parrot-Lopez, Hélène
, p. 241 - 245 (2003)
A new series of fluorinated amphiphilic β-cyclodextrin derivatives has been synthesized. The strategy is based on the modification of the C-6 position of the mono-6-deoxy-6A-para-tolylsulfonyl, di-6A, 6D-deoxy-6A, 6D-(para-tolylsulfonyl) and heptakis-(6-deoxy-6-iodo)-β-cyclodextrin precursors. The synthesis lead to mono-perfluoroalkylthio-, di-perfluoroalkylthio- and heptakis-perfluoroalkylthio-β-cyclodextrin in excellent yields (90-99%).

Qing, Feng-Ling,Ji, Min,Lu, Ronghua,Yan, Kelu,Mao, Zhiping
, p. 139 - 141 (2002)
A new kind of perfluoroalkyl-containing multifunctional groups compound was designed. Treatment of 1H.1H.2H.2H-perfluorooctyltri- chlorosilane (4) with allylmagnesium bromide provided key intermediate 1H,1H,2H,2H-perfluorooctyltriallylsilane (2). Hydroboration followed by oxidation, epoxidation and dihydroxylation of 2 gave perfluoroalkyl-containing multifunctional groups compound 1a, 1b and 1c, respectively.

Paragraph 0023; 0026, (2019/01/06)
The invention relates to the technical field of preparation of new fluorine-containing materials, particularly to an environmentally friendly preparation method of fluorine-containing acrylate. The environmentally friendly preparation method comprises: carrying out a reaction on short-chain perfluoroiodoalkane and ethylene, separating, and purifying to obtain perfluoroalkylethyl iodide; carrying out hydrolysis on the perfluoroalkylethyl iodide, separating, and purifying to obtain perfluoroalkylethanol; and carrying out a reaction on the perfluoroalkylethanol and acrylic acid, separating, and purifying to obtain the product. According to the present invention, the perfluorooctyl-free product is synthesized, the potential risk of PFOA production cannot exist, and the obtained product is theenvironmentally friendly product, and meets the national industrial policy; the preparation method is simple, and is suitable for industrial production; and the reaction conversion rate is high, and the purity of the intermediate product is high, such that the subsequent reaction is easily performed, the yield is easily increased, and the cost is reduced.
Crosslinking of fluoroelastomers by "click" azide-nitrile cycloaddition
Tillet, Guillaume,Lopez, Gérald,Hung, Ming-Hong,Améduri, Bruno
, p. 1171 - 1173 (2015/04/14)
A fluoroelastomer that bears pendant nitrile groups is crosslinked with a telechelic bis-azido fluorinated curing agent by "click" azide-nitrile cycloaddition. Thermogravimetric analyses of the resulting press cured films reveal an improvement by 20 C of the thermal degradation profile under air, compared to that of the corresponding uncured fluoroelastomer.
