WebPCC is soluble in many organic solvents, and especially dichloromethane at room temperature has been used in most cases, whereas DMF promotes the over-oxidation of primary alcohols into carboxylic acids. PCC is more acidic than PDC, but acid-labile compounds can be oxidized in the presence of sodium acetate or other buffers such as … 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.
