    Description / Table of Contents: Abstract Decaphenylcyclopentasilane reacts with anhydrous HJ in a sealed tube to give phenyliodocyclopentasilanes and benzene, and the degree of phenyl cleavage was found to depend on the reaction time. The corresponding methoxyphenylcyclosilanes are obtained in the reaction with methanol. Hydrolysis yields a yellow, fluorescent, polymeric compound containing Si5-rings coupled by oxygen. The colour of the hydrolysis products is discussed in connection with pertinent results in siloxene chemistry.
    Notes: Zusammenfassung Dekaphenylcyclopentasilan reagiert mit wasserfreiem HJ im Bombenrohr unter Benzolabspaltung zu Phenyljodcyclopentasilanen. Der Grad der Phenylabspaltung hängt von der Reaktionszeit ab. Reaktion mit Methanol führt zu entsprechenden Methoxyphenylcyclopentasilanen. Die Hydrolyse ergibt gelbe, fluoreszierende, polymere Hydrolysenprodukte, in denen Si5-Ringe über Sauerstoff verknüpft sind. Die Farbe der Hydrolysenprodukte wird im Zusammenhang mit den Ergebnissen der Siloxenchemie diskutiert.
