| Abstract: | Preparation and Properties of Some Highly Chlorinated Oligosilanes Tetrakis(trichlorosilyl)silane (neo-Si5Cl12) is cleaved by HCl in SiCl4 solution to tris(trichlorosilyl)silane, HSi(SiCl3)3, and SiCl4. HSi(SiCl3)3 and bis(trichlorosilyl)silane, H2Si(SiCl3)2, can also be prepared in good yield by reaction of the methoxy compounds HSi[Si(OCH3)3]3 and H2Si[Si(OCH3)3]2 with BCl3. The mass, 1H-n.m.r., and vibrational spectra of HSi(SiCl3)3 and H2Si(SiCl3) as well as some 1H-n.m.r. data of HClSi(SiCl3)2, HCl2SiSiCl3 and H2ClSiSiCl3 are reported and discussed. An improved synthesis for neo-Si5Cl12 is given. |
