Urea Hydrogen Peroxide

A metal-free, environmentally benign oxidation of substituted sulfides directly to their corresponding sulfones is described. Using urea-hydrogen peroxide and phthalic anhydride in ethyl acetate clean conversion into the sulfone was achieved without observation of the possible sulfoxide oxidation product.
