A novel binuclear iron(III)-salicylaldazine complex has been synthesized and characterized by various techniques such as IR and UV–Vis spectroscopy and X-ray crystallography. The catalytic oxidation of sulfides in the presence of the aforementioned complex was explored at room temperature using urea hydrogen peroxide (UHP) as an oxidant. Effects of different reaction conditions consisting catalyst and oxidant amount, solvent effect and reaction time on the catalytic activity and selectivity in the reaction of methylphenylsulfide oxidation has been surveyed. Perfect selectivity toward sulfoxide was achieved after 15 min in CH3CN by choice of a properly optimized reaction condition.

The title reaction shows first order dependence each in and and the active oxidant species is found to be HNO3.The reaction involves an electron transfer from the sulphoxide to the oxidant resulting in the formation of a radical cation in the rate-determining step, which gives rise to a dication in a fast step followed by hydrolysis and deprotonation to form the sulphone.
