Abstract

The nanoporous chromium carboxylate MIL-101 with coordinatively unsaturated chromium sites has been shown to be active in the sulfoxidation of aryl sulfides with H₂O₂ to selectively produce the corresponding sulfoxides. Interestingly, the electron-releasing groups in the oxygenation reaction of para-X-phenylmethyl sulfoxides (X-Ph-S-CH₃, X = CH₃, H, NO₂, and CN) enhanced the oxidation reactivity in 1:1 mixtures of X-Ph-S-CH₃:H-Ph-S-CH₃. Moreover, the ¹⁸O-labeled experiments to understand the source of oxygen in sulfoxide products proved that the oxygen atom in the sulfoxide product was entirely derived from H₂O₂.
