Summary

The synthesis and structure of octakis[4–(trimethylsilylethynyl)phenyl]-octasilsesquioxane (l), the first representative of a new class of octasilsesquioxanes bearing ridid π-conjugated substituents, is described. Furthermore we present the synthesis and structure of octakis(tetracarbonylcobaltio)octasilsesquioxane (2). In combination with triphenylphosphine, 2 shows catalytic activity in the hydroformylation of 1–hexene.
