Abstract

Mild and easy deprotection of benzylic dioxolanes to carbonyl compounds (in refluxing dry acetone) and trimethylsilyl ethers to alcohols in acetonitrile at ambient temperature has been carried out in excellent yields under K5CoW12O40·3H2O (0.01 molar equiv.) catalysis. © 2001 Elsevier Science Ltd.
