The use of a 50% aqueous methonolic solution of Oxone is described for the
selective cleavage of primary tert-butyldimethylsilyl and aryl ethers at ro
om temperature. This method enables one to deprotect tert-butyldimethylsily
l ethers of primary alcohols in the presence of tert-butyldimethylsilyl eth
ers of secondary and tertiary alcohols and phenols. The silyl ethers of phe
nols were deprotected at longer reaction times.
