TES- and TBS-protected alcohols undergo deprotection in good to excellent yield upon heating with 1equiv of BiOClO4-xH2O in CH 2Cl2. TBDPS- and TIPS-protected 2°alcohols are more resistant to deprotection. The use of this method for selective desilylation is, however, limited to the deprotection of alkyl silyl ethers in the presence of TBDPS-protected phenols.
