Reactions with pcc
WebFeb 4, 2024 · PCC was invented as a workaround to this problem: it works as a reactant in anhydrous enviroment, hence stopping the reaction at the aldheyde stage. An alternative way to see PCC is to follow its preparation: if you add C r O X 3, H C l and pyridine, PCC is formed. If you add C r O X 3, acid and water, chromic acid is formed. WebSep 9, 2011 · Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids. Similar to or the same as: CrO 3 and pyridine (the Collins reagent) will also oxidize primary …
