Benzoins are oxidized to benzils in excellent yields by 0.4 equivalents of Bi(NO3)3·5H2O and 4 mol% of Cu(OAc)2. Bi(NO3)3·5H2O is a stable, inexpensive, commercially available solid. The relatively low cost and low toxicity of bismuth(III) nitrate makes this procedure a particularly attractive method for oxidation of benzoins.
