Для экспериментальных целей нужен пентасилан [pentasilane; Si5H12; 5 гр.]. Есть ли возможность его купить/синтезировать?
И сколько это удовольствие может стоить?
Буду благодарен за любую информацию.
Translated Abstract
Contributions to the Chemistry of Silicon and Germanium. XXX. Photochemical Disproportionation of iso- and n-Pentasilane Preparation of Some New Hepta- and Octasilanes
Solutions of iso- and n-pentasilane in 2,3-dimethylbutane were irradiated at room temperature by UV-light. The photolytic decomposition of the pentasilanes to higher and lower homologes was controlled by gas chromatography. The main reaction can always be described as disproportionation of the pentasilanes to trisilane and branched heptasilanes, or disilane and branched octasilanes. The new hepta- and octasilanes 3,3-disilylpentasilane and 2,3,3-trisilylpentasilane, obtained from iso-pentasilane, as well as 3-silylhexasilane and 4-silylheptasilane, obtained from n-pentasilane, were isolated and characterised by 1H-NMR, Raman and mass spectrocsopy.
