Highly selective and efficient oxidation of sulfides with an eco-friendly oxidant (urea hydrogen peroxide (UHP)) in the presence of meso-terakis(4-hydroxyphenyl)porphyrinatomanganese(III) acetate supported on multi-wall carbon nanotubes (MnTHPPOAc@MWCNT) at room temperature in ethanol has been investigated. 91 % conversion for methyl phenyl sulfide with 100 % selectivity for sulfoxide was obtained after 30 minute at room temperature. The effect of the different reaction conditions such as reaction time, solvent, acetic anhydride (as oxidant activator) amount of oxidant and co-catalyst on the oxidation of methyl phenyl sulfide was studied. The recycled catalysts keep constant of conversion yield up to five cycles.
