SnO₂ Nanoparticles: Preparation and Evaluation of their Catalytic Activity in the Oxidation of Aldehyde Derivatives to their Carboxylic Acid and Sulfides to Sulfoxide Analogs

Abstract

A variety of aromatic and aliphatic aldehydes were converted to the corresponding carboxylic acid derivatives with 30% H₂O₂ and tert-butyl hydroperoxide as the oxidant in the presence of a catalytic amount of SnO₂ nanoparticles as a precursor. These nanoparticles were also used for the efficient catalytic oxidation of sulfides to sulfoxides using 30% H₂O₂. The present methodology offers several advantages such as applicability to a wide range of aldehydes/ sulfides, convenient work-up, mild reaction conditions as well as good yields and reasonable time of the reactions.
