The use of a 0.25M CH3OH CCl4(1:1) solvent mixture under ultrasound for the selective deprotection of tert-butyldimethlysilyl ethers of benzyl alcohols is described. This method enables to deprotect tert-butyldimethlysilyl ethers of primary alcohols, whereas tert-butyldimethlysilyl ethers of secondary and tertiary alcohols were stable under the reaction condition.
