Silica chromate as an oxidising agent for the chemoselective oxidation of alcohols and the oxidative deprotection of trimethylsilyl ethers

Silica chromate easily converts primary and secondary alcohols to corresponding carbonyl compounds in the presence of wet SiO₂ both in dichloromethane and under solvent-free conditions at room temperature with good to excellent yields. Primary and secondary trimethylsilyl ethers were converted into the corresponding carbonyl compounds or alcohols by using silica chromate and wet SiO₂ in dichloromethane at room temperature with good to excellent yields
