Abstract / Description of output
The trisilanol (c-C5H9)(7)Si7O9(OH)(3), generated from the hydrolytic condensation of cyclopentyltrichlorosilane, is converted in excellent yield to a new siloxane 3-endo-tert- butyldimethylsiloxy-1,3,5,7,9,11,14-heptacyclopentyltetra- cyclo[7.3.3.1(3,14).1(5,11)]heptasiloxane [(c-C5H9)(7)Si7O9 (O)(OSi-Me-2 Bu-t) or C41H78O11Si8] in two high-yield steps. It is highly unusual for a polyhedral oligosilsesquioxane to give such well diffracting crystals, and even more so for it to crystallize virtually without disorder. Molecules of this siloxane occur in the crystal as isolated units, free from the silanol hydrogen-bonding interactions that dominate the structural characteristics and associated reaction chemistry of the parent polysilanols.
