PREPARATION OF BENZILS BY OXIDATION OF BENZOINS WITH CHROMIC ACID SUPPORTED ON ALUMINUM SILICATE

摘要

The preparation of benzils by oxidation of corresponding benzoins using chromium trioxide supported on aluminum silicate reagent under heterogeneous conditions and reflux in yields between 82-90% is described. The present oxidations are completed within 5 h, and it is an extension of our previous work as well.
