- Study of the alkylation of chlorosilanes. Part II. Synthesis of (fluoroalkyl)chlorosilanes and tetra(fluroalkyl)silanes via hydrosilylation
-
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(dimethoxy)(methyl)silanes (1H,1H,2H,2H-henicosafluorododecyl(dimethoxy)(methyl)silane, C10F21C2H4Si(CH3)(OCH3)2, 1H,1H,2H,2H-heptadecafluorodecyl(dimethoxy)(methyl)silane, C8F17C2H4Si(CH3)(OCH3)2, 1H,1H,2H,2H-tridecafluorooctyl(dimethoxy)(methyl)silane, C6F13C2H4Si(CH3)(OCH3)2, and 1H,1H,2H,2H-nonafluorohexyl(dimethoxy)(methyl)silane, C4F9C2H4Si(CH3)(OCH3)2), were prepared by the hydrosilylation of dichloro(methyl)silane with the corresponding 1H,1H,2H,2H-polyfluoro-1-alkene in the presence of hydrogen hexachloroplatinate(IV), followed by the reaction with sodium methoxide.The surface modification of glass plate was attempted uisng 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 oxidation resistance of the modified glass surface was also investigated.
