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
三种类型的支链型多氟烷基硅烷,三氯[4,4-双(三氟甲基)-5,5,6,6,6,7,7,7-七氟庚基]硅烷(D3CL3),一氯二甲基[4,4-双(三氟甲基) -5,5,6,6,7,7,7,7-七氟庚基]硅烷(D3CL),三乙氧基[4,4-双(三氟甲基)-5,5,6,6,7,7,7,7-七氟庚基]硅烷(D3Et3),可以在六氯铂酸氢盐(IV)存在的情况下,使用支链型多氟烯烃和相应的硅烷的硅氢化反应来合成。4,4-双(三氟甲基)-5,5,6,6,7,7,7-七氟-1-庚烯与硅烷的氢化硅烷化反应仅产生高区域选择性的β-加成化合物。通过MM2计算,发现支链-多氟烷基硅烷在季碳处具有弯曲结构。
