During our investigation of the chemistry of bis-gemdiphenylsulphinyl and sulfonyls [1], we have prepared the 4-phenyl-2,2′-bis (phenylsulfonyl)butane from the corresponding thioketal by dimethyldioxirane oxidation [2]. Procedure of synthesis: To a stirring solution of thioketal (I) 0.7 g. (2 mmol) in dry acetone (40 mL) at -78 oC, a solution of dimethyldioxirane 85 mL (0.043 mmol /mL acetone) were added dropwise. Then, the reaction mixture was stirred to reach the room temperature. After evaporation of the solvent under vacuum, the residue was chromatographed on a silica gel column eluting with a mixture of CHCl3: AcOEt: petroleumether (30:5:65) to yield 0.72 g. (87%) of the compound (II) as white crystals.
