A new mild method for protecting alcohols as t-butyl ethers is reported. The reaction proceeds with Mg(ClO4)(2) and Boc(2)O and shows general applicability. The deprotection of t-butyl ethers has also been revisited. Preliminary results indicate the CeCl3.7H(2)O/Nal system is a very suitable catalyst for their removal.
