WebPyridinium chlorochromate (PCC), introduced by Corey and Suggs in 1976 (2), has surpassed the Jones reagent (chromic acid) (3) and the Collins reagent (4) (chromium trioxide/ pyridine complex) in frequency of usage in contemporary organic synthesis. When compared with the Jones reagent, PCC is milder and less acidic and promotes fewer side ... WebMost chromate (VI) reagents work via a common mechanism – formation of a chromate ester followed by oxidative elimination of Cr (IV) and the oxidized alcohol product. General comments PDC and the related PCC are among a range of Cr (VI) oxidants available. Other variants exist with modifications like amine ligands etc.
