Cyclic 1,3,5,7-tetrakis(trimethylsilyl)tetraphenyltetrasilsesquioxane (T4OTMS), 3,7,14-tris(trimethylsilyl)heptaphenyltricyclo[7.3.3.15,11]heptasilsesquioxane (T7OTMS), and 5,11,14,17-tetrakis(trimethylsilyl)octaphenyltetracyclo[7.3.3.33,7]octasilsesquioxane (DDT8OTMS) were found to be formed by the hydrolysis of completely condensed polyhedral oligomeric silsesquioxanes (POSS) followed by trimethylsilyl (TMS)-capping. The reaction was shown to be a reshuffling process by the scrambling of substitutents in co-hydrolysis of differently substituted POSS.
