The Reactivity of Silyl Ethers to the Swern Reagent

The activated Me2SO reagent , 'Swern reagent'> oxidises the trimethylsilyl ethers of primary and secondary alcohols directly to the corresponding carbonyl compound.Useful selectivity is possible where competing ether groups possess large differences of steric hindrance.Dimethyl-t-butylsilyl ethers are unaffected by this reagent.
