Description générale

Sodium hypochlorite (NaOCl) is a commonly used reagent in organic synthesis for many oxidation and chlorination reactions.

Application

Sodium hypochlorite solution can be used as an oxidizing agent for the oxidation of:      
  • Primary alcohols to aldehydes or carboxylic acids and secondary alcohols to ketones.     
  • Aryl aldehydes to the corresponding acids in the presence of a phase-transfer catalyst.      
  • Ethers to esters by careful pH control (pH range of 8–9.5),

It can also be used as a reagent in the:      
  • Epoxidation of enones and polycyclic arenes.      
  • Oxidative degradation reaction      
  • N-Chlorination of primary and secondary amines
  • Enantioselective epoxidation of α, β-unsaturated ketones      
  • Asymmetric dihydroxylation of olefins in the presence of an osmium catalyst      
  • Chlorination of allylic carbons in the presence of CeCl3

Caractéristiques et avantages

  • Readily available reagent      
  • Easily handled oxidizing agent      
  • No phase-transfer catalyst is necessary for the oxidation of substrates in the pH range 10–11     
  • Simplified waste disposal and lower toxicity
