Quinolinium dichromate

용도Quinolinium dichromate (QDC) is found to be a mild reagent for the oxidation of organic compounds. It is particularly effective for oxidizing primary and secondary alcohols to their corresponding aldehydes and ketones, respectively. Like other chromium(VI) reagents, QDC is suitable for laboratory research and development as well as for chemical and pharmaceutical synthesis processes.

Quinolinium dichromate was prepared according to the procedure describe by Balasubramanian et al. [5]Synthesis of Quinolinium Dichromate: Quinidine (28 mL, 0.2 mol) was added slowly to a cooled solution of chromium trioxide (CrO₃, 20 g, 0.2 mol) in water (20 mL). After stirring for 0.5 hours, the reaction mixture was diluted with acetone (40 mL) and cooled to -15 °C. The yellow crystals that formed were collected by filtration, washed with acetone, and then recrystallized from water. The product was dried under vacuum for approximately 2 hours. Yield: 88%. Melting point: 150–151 °C.
