PCC is a mild oxidizing agent which can be used to oxidize primary alcohols to aldehydes and secondary alcohols to ketones.1

Summary

The reaction entry summary. Find the general scheme and full summarized mechanisms here.

​
General Scheme

This section briefly summarizes what can and cannot undergo reactions.

  • 1° Alcohols (Primary) get oxidized to Aldehydes.
  • 2° Alcohols (Secondary) get oxidized to Ketones.
  • 3° Alcohols (Tertiary) do not get oxidized at all.

​
General Mechanism

This section briefly summarizes steps to find the product and perform the mechanisms.

Quick steps to finding the product for any alcohol

  1. Identify the reagents.
  2. Assign side chains (non alcohol part).
  3. Selectively convert Alcohol to correct product based on alcohol type. Nothing else.
  4. Keep the side chains (non alcohol part) the same and piece together the full molecule together again.
Always remember to repeatedly practice your mechanisms and getting your reagents correct. Take advantage of our materials and/or keep practicing on a whiteboard or paper until you get it right every single time.
