Resumen:
A range of sulfides can be selectively oxidized to the corresponding sulfoxides in good yields using catalytic quantities of heterocyclicamine salts (quinoline, cinchonine, and cinchonidine) of Keggin heteropolyacids with different green oxidants. The cinchonine heteropolyacidcatalyst is easily recoverable and reusable without loss of its catalytic activity, and an enantiomeric excess can be obtained.
