O-Xylylenebis(Triphenylphosphonium) Dichlorochromate: a Selective and Efficient Reagent for Oxidation of Alcohols, Trimethylsilyl Ethers and Thiols

3 Abstract: Alcohols, trimethylsilyl ethers and thiols were efficiently converted to their corresponding carbonyl and disulfides compounds using o-xylylenebis (triphenylphosphonium) dichlorochromate (XTPPDCC). This reagent can selectively oxidize thiols to disulfides in the presence of alcohols and trimethylsilyl ethers in acetonitrile at room temperature.
