Synthesis of novel organic-inorganic hybrid cages via cobalt-catalyzed cyclotrimerization of dimethylethynylsilyl groups on a silsesquioxane
Novel organic-inorganic hybrid cages composed of a half-caged silsesquioxane skeleton and a benzene ring have been synthesized by cobalt-catalyzed intramolecular cyclotrimerization of a silsesquioxane bearing three dimethylethynylsilyl groups.
