The synthesis and structural characterization of tetra(1H,1H,2H,2H-polyfluoroalkyl)silanes with the same or different chain lengths CnF2n+1 linked to Si (1nG) is reported.When the synthesis was effected from chlorosilanes were obtained.The last fluorinated chain was introduced either via a fluoroalkyllithium reagent or by hydrosilylation of the trialkylsilanes.Some properties and characterization by 1H, 19F and 29Si NMR spectroscopy of the 1H,1H,2H,2H-polyfluoroalkylsilanes are described.

Page/Page column 8-10, (2008/06/13)
The present invention relates to a process for preparing silicon compounds bearing fluoroalkyl groups by hydrosilylation of a fluoroolefin in the presence of a hydrosilylation catalyst, which comprises initially charging and heating a hydrogenchlorosilane, then metering in the fluoroolefin and reacting the reaction mixture and subsequently isolating the hydrosilylation product.

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.
Process for preparing fluoroalkyl-containing organosilicon compounds, and their use
-
, (2008/06/13)
Fluoroalkyl organosilicon compounds are prepared by reacting fluoroolefins with organosilicon compounds that contain at least one H--Si group, in the presence of a Pt(0) complex catalyst. Further, fluoroalkylalkoxy organosilicon compounds are prepared by esterifying fluoroalkyl organosilicon compounds. The process proceeds uniformly under mild conditions with high yields and selectivities.

The hydrosilylation of various fluorinated olefins and of a diene with different chlorosilanes and with a tri(fluoroalkyl)silane, in the presence of a peroxide or a Pt catalyst, is reported.The reactivity is influenced considerably by the structure of the silane and of the fluorinated olefin.The following (fluoroalkyl)chlorosilanes and (fluoroalkyl)-α,ω-chlorodisilanes are described; C6F13(CH2)nSiR1R2Cl where n = 2 or 3 and (ClR1R2SiC2H4C3F6)2 with R1 = R2 = Cl, R1 = Cl and R2 = CH3 or C2H4CF3, R1 = R2 = CH3 and R1 = CH3 and R2 = C6H5.Three new tetra(fluoroalkyl)silanes have also been synthesized.All the products were characterized by 1H, 19F and 29Si NMR spectroscopy.

Four silane coupling agents, (1H,1H,2H,2H-polyfluoroalkyl)trimethoxysilanes ((1H,1H,2H,2H-henicosafluorododecyl)trimethoxysilane, C10F21C2H4Si(OCH3)3, (1H,1H,2H,2H-heptadecafluorodecyl)trimethoxysilane, C58F17C2H4Si(OCH3)3, (1H,1H,2H,2H-tridecafluorooctyl)trimethoxysilane, C6F13C2H4Si(OCH3)3, and (1H,1H,2H,2H-nonafluorohexyl)trimethoxysilane, C4F9C2H4Si(OCH3)3), were prepared by the hydrosilylation of trichlorosilane with the corresponding 1H,1H,2H,-polyfluoro-1-alkene in the presence of hydrogen hexachloroplatinate-(IV), followed by reaction with sodium methoxide.The surface modification of glass plate was attempted using these products.From measurements of the contact angles θ (deg) of water and oleic acid against a modified glass plate surface, the coupling agents were found to have high modification ability.The modification produced a glass surface with high oxidation resistance.
