Abstract
A new chromium(VI) reagent, 3,5-dimethylpyrazolium fluorochromate, C5H8N2H[ CrO3F] (DmpzHFC), has been developed by reacting dmpz with CrO3 and aqueous HF for the selective oxidation of primary, secondary and allylic alcohols to the corresponding carbonyl compounds, polycyclic hydrocarbons to cyclic ketones and allylic Delta (5) steroids to the corresponding alpha,beta -uns aturated ketones.
