摘要：
Selective oxidation of -hydroxy ketones to the corresponding -diketones with chromium trioxide supported on kieselghur reagent under heterogeneous conditions and reflux is described, and this procedure is an extension of application for this supported reagent as well. The present oxidations are completed within 30 minutes with the yield between 83-93%. The main advantage of this oxidation is that the reaction time is much shorter as compared to the other reported chromium (VI)-based reagents.
