redox-neutral sulfonylative coupling of boronic acids and ammonium salts to afford (hetero)aryl alkyl sulfones by using potassium metabisulfite has been realized. Various functional sulfones were obtained by using commercially available and air-stable CoCl2 in combination with phenanthroline ligand. In addition, various carbon based electrophiles, including diaryliodoniumsalts, heteroaryl halides, and

An efficient method for the synthesis of sulfones has been developed using sugar derived cis-dioxo molybdenum(VI) complex as catalyst and urea hydrogen peroxide as oxygen source. Present method is highly specific for sulfide oxidation irrespective of presence of alkene and aldehyde groups in the same molecule. Synthesis of fifteen sulfones have been reported with 82–98% isolated yields and the catalyst
