Synthesis of polyhedral phenylsilsesquioxanes with KF as the source of the fluoride ion.
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.
