Three types of branched-type polyfluoroalkylsilanes, trichloro[4,4-bis(trifluoromethyl)-5,5,6,6,7,7,7-heptafluoroheptyl] silane (D3CL3), monochlorodimethyl[4,4-bis(trifluoromethyl)-5,5,6,6,7,7,7-heptafluoroheptyl] silane (D3CL), triethoxy[4,4-bis(trifluoromethyl)-5,5,6,6,7,7,7-heptafluoroheptyl]silane (D3Et3), could be synthesized using the hydrosilylation reaction of the branched-type polyfluoroalkene and corresponding silanes in the presence of hydrogen hexachloroplatinate (IV) as a catalyst. The hydrosilylation reaction of 4,4-bis(trifluoromethyl)-5,5,6,6,7,7,7-heptafluoro-1-heptene with silanes produced only β-addition compounds highly regioselectively. From the MM2 calculation, it was found that the branched-polyfluoroalkylsilane has a bent structure at quaternary carbon.

Methods for syntheses of new polyfluorinated compounds, viz., silanes containing substituents CF3CF2CF2C(CF 3)2(CH2)3 (RF) at the silicon atom and 1,3,5-tris(RF)-1,3,5-trimethylcyclotrisiloxane that can be used for the synthesis of fluorocontaining oligo- and polysiloxanes of different structure, were developed. The polymerization of cyclotrisiloxane in the presence of 1,3-divinyltetramethyldisiloxane gave linear oligomers, whose chain contain -(RF)Si(Me)O- units.
