General description
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.
Application
Potassium nitrosodisulfonate can be used as an oxidizing reagent for the oxidation of:
- Aromatic amines to their corresponding quinones.
- Hydroethidine to 2-hydroxyethidium.
- Tyrosine to o-quinones.

Described herein are structure-activity studies of new antitumor agents based on the pyrrolo[1,2-a]benzimidazole (PBI) ring system. These compounds were designed as new DNA cross-linkers mimicking the mitomycin antitumor agents. Actually, the PBI derivatives were found to have anthracycline-like features: (i)
