V(HSO4)3 promoted oxidation of alcohols and trimethylsilyl, tetrahyropyranyl and methoxymethyl ethers with Cu(NO3)2·3H2O in the absence of solvent

V(HSO4)3 has been found to be an efficient reagent for the promotion of the oxidation of alcohols and trimethylsilyl, tetrahydropyranyl and methoxymethyl ethers to their corresponding carbonyl compounds with Cu(NO3)2·3H2O in the absence of solvent.
