    Oligosilyl-Quecksilber und -Alkalimetallverbindungen (1986)
    Springer
    Monatshefte für Chemie 117 (1986), S. 721-728 
    Details
    ISSN: 1434-4475
    Keywords: Oligosilanes ; Potassium silyl compounds ; Mercury silyl compounds
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Oligo-silyl-mercury compounds (Si nR 2n+1)2Hg (R=aryl, halogens) are synthesized from the siliconmonohydrides by reaction with (t-Bu)2Hg and characterized. Treatment of the Silyl-mercury compounds with Na/K- alloy yields the corresponding alkali metal derivatives. Both reactions are very well suitable for the synthesis of oligosilanes.

    UV/Vis-spektroskopische Untersuchungen an Cyclosilanderivaten (1988)
    Springer
    Monatshefte für Chemie 119 (1988), S. 873-887 
    Details
    ISSN: 1434-4475
    Keywords: Cyclopolysilanes ; UV/vis-spectra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract UV/Vis-spectra of Cyclosilanes (SiX 2) n withX=Cl, Br, I, OMe andn=4, 5, 6 are recorded and interpreted qualitatively. The spectra exhibit increasing influence of the substituents on the Si-Si-bond system within the rings in the order Cl ≈ OMe → Br → I. At the low energy side of the spectra weak absorption bands, possibly due to intramolecular charge transfer transitions, appear. The strong inductive effect of the electronegative substituents is documented by a marked increase of the first IP's compared to permethylcyclosilanes.
