摘要
An effective oxidation of benzoins into corresponding benzils with manganese dioxide supported on aluminum silicate reagent under heterogeneous and reflux is described. The present oxidations are completed within 8 hours with the yield between 82-92%. For the reaction with manganese dioxide in the absence of support the isolation of products from the ensuing residues is rendered more difficult, however, in the current procedure it turns out to be very profitable in the work-up, which becomes reduced to a mere filtration.
