  Synthese und eigenschaften funktioneller polysilane: Die tetrasilane MeSi(SiMe2X)3 und hexasilane (Me2XSi)2MeSiSiMe(SiMe2X), X=Me, H, F, Cl, Br, I

  摘要：

  Besides MeSi(SiMe(3))(3), the hexasilane [(Me(3)Si)(2)MeSi](2) is formed in astonishingly high yields in the reaction of a mixture of MeSiCl(3) and Me(3)SiCl with lithium, The permethylated silanes are easily functionalised with Me(3)SiCl/AlCl3, chlorinating all Me(3)Si-groups to form Me(2)ClSi. The reduction with LiAlH4 yields the Me(2)HSi-compounds, which are easily brominated and iodinated with CBr4 and HCI3. A subsequent reaction with ZnF2 gives the fluorocompounds. The Si-29-spectra, including (SiSi)-Si-29-Si-29 coupling constants, are reported and substituent effects are discussed.
