Abstract:
Two prismatic phenyl‐ (PhSiO1.5)14(CuO)7 (1, 29 % yield) and methyl‐ (MeSiO1.5)14(CuO)7 (2, 19 % yield) heptacoppersilsesquioxanes were obtained by the interaction of Cu,Na‐based cage silsesquioxanes [(RSiO1.5)12(CuO)4(NaO0.5)4] (R = Ph, Me) with 4,4′‐bipyridine and pyrazine, respectively, acting as “silent witness” ligands. Unusual molecular topologies of both compounds 1 and 2, which are the first representatives of cage silsesquioxanes with seven metal ions in their cores, were established by X‐ray diffraction studies. Complex 1 was found to be an active precatalyst in the oxidation of alkanes and 1‐phenylethanol to alkyl hydroperoxides and acetophenone, respectively. Alkanes were oxidized by hydrogen peroxide, and the alcohol was oxidized by tert‐butyl hydroperoxide.
