YELLOW-ORANGE TO ORANGE CRYSTALS OR CRYST. POWDER

Benzyltriethylammonium Chlorochromate is a mild and neutral oxidizing agent for benzylic and allylic alcohols.

Preparative Method: Chromic Acid (10 g, 0.1 mol) in 3 M HCl (200 mL) is added to an aqueous solution (250 mL) of Benzyltriethylammonium Chloride (22.7 g, 0.1 mol). The crude product precipitates and can be recrystallized from acetone water, yielding 86%. It was demonstrated that the compound obtained under these conditions is benzyltriethylammonium chlorochromate.

Benzyltriethylammonium chlorochromate is a stable orange crystalline solid. No data about storage and precautions have been reported. Chromium(VI) derivatives are reported to be toxic agents. The reagent should be handled in a fume hood.
