资源简介：
Novel phthalimide and o-sulfobenzimide-functionalized
silsesquioxanes were successfully synthesized via nucleophilic substitution
reactions from octakis(3-chloropropyl)octasilsesquioxane. Surprisingly,
the formation of deca- and dodecasilsesquioxanes cages was discovered
during substitution with phthalimide, but only octasilsesquioxane
maintained a cage in the o-sulfobenzimide substitution
reaction. Moreover, we report the electronic effect of nitrogen nucleophiles
to promote cage-rearrangement of inorganic silsesquioxane core for
the first time. Structures of products were confirmed by 1H, 13C, and 29Si NMR spectroscopy, ESI–MS
analysis, and single-crystal X-ray diffraction.
