Descrição geral

Potassium nitrosodisulfonate is an oxidizing reagent that can be used to convert phenols, naphthols, and anilines to quinones, benzylic alcohols to aldehydes or ketones, and amino acids to α-keto acids. It can also be used for the preparation of heterocyclic quinones and oxidative aromatization[1].

Aplicação

Potassium nitrosodisulfonate can be used as an oxidizing reagent for the oxidation of:
  • Aromatic amines to their corresponding quinones[2].
  • Hydroethidine to 2-hydroxyethidium[3].
  • Tyrosine to o-quinones[4].

Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant, though salcomine and alkali did not catalyze the oxidation by molecular oxygen. Bisphenol A, bisphenol B, and 3,4'-(1-methylethylidene)bisphenol were converted to their monoquinone derivatives in
