The preparation of benzils by oxidation of corresponding benzoins using ferric (III) nitrate nonahydrate supported on aluminum silicate reagent under heterogeneous conditions and reflux in yields between 82–95% is described. The main advantage of this oxidation is that the reaction time is much shorter as compared to the other reported ferric (III) nitrate nonahydrate based reagents, and it is an extension of application for the ferric (III) nitrate nonahydrate supported on aluminum silicate reagent as well.
