    Description / Table of Contents: Preparation and Spectroscopie Properties of Some Perbromo- and PeriodooligosilanesThe cleavage of octaphenylcyclotetrasilane and decaphenylcyclopentasilane with Iodine, phosphorus pentabromide and bromine and the successive reaction with HBr/AlBr3 or HI/AlI3 give n-Si4Br10, n-Si5Br12, n-Si4I10, and n-Si5I12. Their IR and Raman spectra are discussed with the aid of a normal coordinate analysis. The spectra of the cyclic iodosilanes Si4I8, Si5I10, and Si6I12, prepared previously [1], are included in the discussion.
    Notes: Die Spaltung von Oktaphenylcyclotetrasilan und Dekaphenylcyclopentasilan mit Iod, Phosphorpentabromid oder Brom und anschließende Umsetzung mit HBr/AlBr3 bzw. HI/AlI3 erlaubt die Darstellung der bisher unbekannten Halogensilane n-Si4Br10, n-Si4I10, n-Si5Br12 und n-Si5I12. Ihre IR- und Raman-Spektren werden mit Hilfe einer Normalkoordinatenanalyse diskutiert. Jene der kürzlich dargestellten [1] cyclischen Iodsilane Si4I8, Si5I10 und Si6I12 werden mit einbezogen.
