Highly efficient oxidation of sulfides to sulfones with tetra-n-butylammonium hydrogen monopersulfate catalyzed by β-tri- and tetra-brominated meso-tetraphenylporphyrinatomanganese(III) acetate Original Research Article

β-tri- and tetrabrominated meso-Tetraphenylporphyrinatomanganese(III) acetate as electron deficient Mn-porphyrins are efficient catalysts for chemoselective oxidation of sulfides to the corresponding sulfones with tetra-n-butylammonium hydrogen monopersulfate in the presence of imidazole.
