Physical and Chemical Properties | Compared with other commonly used chromium-containing oxidants such as jons reagent and Colljn reagent, PCC has the characteristics of strong oxidation ability, good selectivity, and the alkene bond of the substrate molecule is not affected in the oxidation process, and easy to operate. In addition, the acidity of the daughter P CC is weak, so those groups that are unstable to the acid can still be preserved during oxidation. |
Use | Usually used to oxidize an allylic methylene group. |
