Abstract :
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.
