Abstract : The factors influencing the formation of octaisopropylocta-silsesquioxane have been investigated. This compound can be brominated by means of N-bromosuccinimide. Chemical evidence and n.m.r. spectroscopy show that bromination occurs in the alpha position of the isopropyl groups. Thin-layer chromatography provided a means of separating and identifying the individual components in brominated octaisopropyl T8 materials and column chromatography was used to isolate other oligomers. Some chemical reactions of the brominated derivatives and several investigations into the possibility of preparing a silazane cage compound are described.
