A new chromium(VI) reagent 3,5-dimethylpyrazolium chlorochromate, C5H8N2H[CrO3Cl] (DmpzHCC), was synthesized and used for the selective oxidation of various organic compounds under solvent-free conditions with high efficiency. This new compound has certain advantages over its companion analogues in terms of controlled acidity, amount of oxidant, lack of solvent, short reaction times, and high yields.
