An improved method for the deprotection of benzyl ethers using a catalytic amount of Co2(CO)8 in the presence of Me2PhSiH and CO (1 atm) is described. The deprotection reaction is compatible with double bond or sulfur-containing substrates. The method also tolerates other functional groups, such as Ac, Piv, and Bz, and shows potential selectivity in perbenzylated monosaccharides.
