Versuchsvorschrift

4-Methylsulfanyl-benzonitrile (250 mg, 1.68 mmol) was dissolved in 12 mL of HOAc. Potassium permanganate (531 mg, 3.36 mmol) was added as an aqueous solution (7-8 mL). After stirring 30 min at RT, NaHSO3 was added with stirring until the brown color of the solution disappeared. The mixture was concentrated and diluted with water. The precipitate was filtered and dried in vacuo to yield 4-methanesulfonyl-benzonitrile (250 mg, 82%) which was used without further purification.
