Pyridinium chlorochromate ( PCC abbreviation, also Corey 's reagent, named after the Nobel laureate Elias James Corey Jr.) is a widely used in organic chemistry, a strong oxidizing agent. It can be used to represent either of primary alcohols, aldehydes ( under anhydrous conditions ) or carboxylic acids. Due to the toxicity and carcinogenicity of chromium ( VI) compounds to be apart from the use of PCC as possible where other methods such as the Swern oxidation or oxidation with TEMPO radical are also suitable.
Representation
Can be represented by the reaction of pyridine, pyridinium chlorochromate, chromium ( VI) oxide, and concentrated hydrochloric acid.
