Nano-TiO2 and Preyssler Dopped Nano-TiO2: A Facile and Efficient Catalyst for the Selective Oxidation of Sulfides to Sulfones and Sulfoxides

A new and efficient synthetic method has been achieved for the selective conversion of sulfides into their corresponding sulfones and sulfoxides using H2O2 in the presence of neat or Preyssler dopped nano-TiO2 as catalyst, respectively. The reaction was performed at room temperature with quantitative yields. The catalyst is reusable without significant loss of activity for the next oxidation reaction.
