WebApr 30, 2014 · General Characteristics. The oxidation of alcohols by PCC (Pyridinium Chlorochromate) or PDC (Pyridinium Dichromate) work s under mild conditions and can be used for compounds containing unstable functional groups. This method is useful to synthesize aldehydes, whereas the Jones and the Sarett-Collins oxidations are better … WebPyridinium chlorochromate ( PCC) is a milder version of chromic acid. PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids. cuny hunter academic schedule

An alternative way to see PCC is to follow its preparation: if you add C r O X 3, H C l and pyridine, PCC is formed. If you add C r O X 3, acid and water, chromic acid is formed. cuny human services

"WebSo this is the PCC reagent, which is a much more mild agent than the Jones reagent. It'll oxidize your primary alcohol and stop at your aldehyde. So let's go ahead and react to ethanol again. This time, we'll use PCC instead of Jones. So if we started with ethanol and we added PCC-- so here we go-- we're going to end up with an aldehyde. " - Reactions with pcc
