The one-pot synthesis of Ph₃SiOH, ^tBu₂Si(OH)₂, (Me₃Si)₃CSi(OH)₃ and (Me₃Si)₃CSiMe₂OH directly from the corresponding bulky silicon hydrides using KMnO₄ is described. The size of the substituents, the silane: KMnO₄ stoichiometry, the solvent and the application of ultrasound were all shown to influence the rate of the reactions.
