Reaction of aldehyde with pcc
WebAcid chlorides can be easily converted to aldehydes by reductive oxidation using LAH and Pyridinum chlorochromate (PCC) or Pyridinum dichromate (PDC). Since this procedure uses no exotic or watched chemicals and since yields are pretty good, this might be another way to our beloved aldehydes. 1 Experimental section WebJan 28, 2024 · PCC oxidizes 1o alcohols one rung up the oxidation ladder, turning primary alcohols into aldehydes and secondary alcohols into ketones.
