Nitric acid in the presence of supported P2O5 on silica gel affords an efficient and mild system for oxidation of organic compounds under solvent-free conditions
This paper describes an efficient and easy method for oxidation of alcohols 1 and sulfides 2 to their corresponding carbonyl compounds 3 and sulfoxides 4 with nitric acid in the presence of supported P2O5 on silica gel under solvent-free conditions in high yields.
