hydrogenosilanes CnF2n+1(CH2)xC2H4Si(CH3)2H with n = 6 or 8 and x = 0 or 1 is presented. Such compounds were prepared in 85%–90% yield by the selective reduction of the corresponding fluorine-containing (dimethyl)chlorosilanes. These chlorinated derivatives were produced by the hydrosilylation of (dimethyl)chlorosilane with perfluoroalkylvinyl, CnF2n+1CHCH2 (x = 0), or allyl, CnF2n+1CH2CHCH2 (x = 1), olefins

Study of the alkylation of chlorosilanes. Part II. Synthesis of (fluoroalkyl)chlorosilanes and tetra(fluoroalkyl)silanes via hydrosilylation
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)n,SiR1R2Cl
