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
