title: Synthesis of polyhedral phenylsilsesquioxanes with KF as the source of the fluoride ion.
abstract: An alternative method for the preparation of polyhedral phenylsilsesquioxanes is reported. Phenylsilsesquioxane resin and freshly hydrolysed phenyltrimethoxysilane was refluxed with various phase-transfer catalysts and potassium fluoride in toluene yielding octaphenylsilsesquioxane, or in a mixture of THF and ethanol yielding dodecaphenylsilsesquioxane.
