What is PDC (Pyridinium Dichromate) and how is it used in organic chemistry reactions?

PDC, or Pyridinium Dichromate, is an oxidizing agent used in organic chemistry reactions to oxidize primary alcohols to aldehydes and secondary alcohols to ketones.

PDC in Organic Chemistry Reactions

PDC, which stands for Pyridinium Dichromate, is a compound used as an oxidizing agent in organic chemistry reactions. This means it is capable of accepting electrons from other compounds, thereby oxidizing them. Pyridinium Dichromate is utilized for the oxidation of primary alcohols to aldehydes and secondary alcohols to ketones, among other applications. It is chosen for its mildness and compatibility with sensitive organic molecules. An example of a strong oxidizing agent in inorganic reactions is potassium dichromate, which is shown in the half-reaction: Cr₂O₇²⁻(aq) +14H⁺¹(aq) +6e⁻ ⇒2Cr³⁺(aq) +7H₂O(l) However, PDC does not act as a reducing agent, catalyst, or solvent in chemical reactions. Its specific role is centered on oxidation processes in organic synthesis.
