The reactions of hydrosilanes with trifluoropropene (TFP) and pentafluorostyrene (PFS) catalyzed by Ru3(CO)12 or RhCl(PPh3)3 give β-Rf-vinylsilane (1) and/or β-Rf-ethylsilane (2) (Rf=perfluorocarbon group).The 1/2 ratio is highly dependent on the nature of hydrosilane used.The ruthenium catalyst favors the formation of 1 compared with the rhodium catalyst.Neither α-Rf-vinylsilane nor α-Rf-ethylsilane was formed at all.Possible mechanisms which can accommodate characteristic features of these reactions are discussed.The hydrosilylation of TFP with dichloromethylsilane catalyzed by PdCl2(PhCN)2/2PPh3 gives the α-adduct (9a) exclusively, and this is transformed to the corresponding dialkoxysilanes, silane diol, oligosilane diols and cyclic oligosiloxanes.
