Thioanisole oxidation with hydrogen peroxide catalyzed by hexadentate 8-quinolinolato manganese(III) complexes

Hexadentate 8-quinolinolato manganese(III) complexes (Q3MnIII) developed by us, with the help of NH4OAC and HOAc, were found to efficiently catalyze the mild oxidation of thioanisole with aqueous hydrogen peroxide in environmentally benign acetone–water media. The ligand's halogen substituents could improve the catalytic efficiency of Q3MnIII complexes, and this is likely that they can strengthen the distorted effect of Q3MnIII, as supported by B3LYP/6-311G (d) calculation. The adjusting effect of additives on this sulfoxidation was also investigated and their mediation mechanisms were proposed.
