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.
Graphical abstractA simple, catalytic and highly chemo-selective oxidation of sulfides to the corresponding sulfones in the presence of β-tri- and tetra-brominated meso-tetraphenylporphyrinatomanganes(III) acetate as electron deficient Mn–porphyrins with tetra-n-butylammonium hydrogen monopersulfate and imidazole was described. A good range of sulfides was selectively oxidized at room temperature in excellent yields and in a very short reaction time.Figure optionsDownload full-size imageDownload as PowerPoint slide
