Nanoparticle catalysed oxidation of sulfides to sulfones by in situ generated H2O2 in supercritical carbon dioxide/water biphasic medium.
In a one-pot reaction, hydrogen peroxide generated from H(2) and O(2) on a Pd catalyst was utilised as oxidant for the TiO(2) catalyzed conversion of a sulfide to a sulfone. This transformation, where two different nanoparticle catalysts were employed in a supercritical carbon dioxide/water biphasic system, demonstrates the potential of compartmentalising catalytic processes in consecutive reactions.
