Abstract
Selective oxidation of benzoins to corresponding benzils using chromium trioxide supported on kieselghur reagent under viscous conditions at room temperature is described. The present oxidations are completed within 1 hour with the yield between 89 and 98%. The main advantage of present oxidation is that the reaction can be carried out under quite milder reaction conditions as compared to the other reported chromium (VI)-based reagents.
