E. Beyou et al., A CONVENIENT APPROACH TO PERFLUORINATED ORGANOSILICONS, PREPARATION OF A FLUORINATED POLYSILOXANE PRECURSOR, Tetrahedron letters, 36(11), 1995, pp. 1843-1844
Addition of perfluoroctyl iodide to the double bonds of vinyltrimethyl
silane and 1,3-divinyltetramethyldisiloxane, followed by a reduction o
f the carbon-iodide bond. gives the corresponding C8F17CH2CH(2)Si= moi
ety. Following this approach. [C8F17-CH2CH2-Si(Me)O](4) a precursor of
highly fluorinated silicones, was conveniently prepared, without usin
g hydrosilylation or Grignard reaction.
