용도Pyridinium dichromate (PDC) is an orange colored solid used as an oxidizing agent. Oxidizing agent for conversion of primary alcohols to aldehydes and ketones, acetals to esters, and didehydroketones to enones in the presence of tert-butyl hydroperoxide. Pyridinium Dichromate may be used as an alternative to PCC in nucleoside and carbohydrate oxidation, particularly for fragile molecules. PDC can also be used in conjunction with tertbutylhydroperoxide for a variety of oxidative transformations.
Pyridinium dichromate can be obtained by gradual addition of a solution of chromic anhydride (Cr2O3) in water to pyridine in ice cold conditions.
