An efficient and convenient procedure for direct esterification of alkyl and aryl silyl ethers with Ac2O and a catalyst system of perchloric acid immobilized on a silica gel (HClO4–SiO2) has been developed. The silyl protecting groups are directly

The fluoride-free one-pot method is environmentally friendly since the silyl protecting groups are transformed into acetates as the sole byproducts, which are readily recoverable and converted back to silyl chlorides as protecting agents by treatment

The transformation of acetonides into acetates is frequently required in synthetic chemistry. An efficient procedure for direct conversion of acetonides into acetates in the presence of HClO(4)-SiO(2) under mild conditions was developed. The acetonid
