The oxidation of sulfides is the most straightforward method for the synthesis of sulfoxides. Racemic sulfoxidation has been studied in solution and on solid phase using several types of oxidizing agents. For example, in solution, H 2 O 2 is one of the most used, 13 but classical oxygen transfer reagents, such as m-CPBA, 14 or ozone 15 have also been examined. On solid phase, there are some references to sulfide oxidation using H 2 O 2 with a catalytic amount of AcOH, ...
