By controlling the ratio of N ‐bromosuccinimide (NBS) to trichloro( p ‐tolyl)silane, [4‐(bromomethyl)phenyl]trichlorosilane and trichloro[4‐(tribromomethyl)phenyl]silane were selectively prepared for the first time. Then, by treating theabove two trichlorosilanes with incompletely condensedsilsesquioxane, R 7 Si 7 O 9 (OH) 3 , a (monobromomethyl)phenyl‐tethered octasilsesquioxane and (tribromomethyl)phenyl‐tethered octasilsesquioxane were easily obtained. Finally, the resulting two compounds were further hydrolyzed to form a (monohydroxymethyl)phenyl‐ and monocarboxyphenyl‐functionalized octasilsesquioxane, respectively.(© Wiley‐VCH Verlag GmbH & Co.
