A sequential one-pot synthesis for the oxidation of primary and secondary tert-butyldimethylsilyl (TBDMS) ethers, using the presence of PhIO or PhI(OAc)2 and catalytic amounts of metal triflates and TEMPO in THF or acetonitrile tolerates acid-sensitive protecting groups and leaves tert-butyldiphenylsilyl ethers and phenolic TBDMS groups untouched.
