    • 4. The solvents were removed under reduced pressure to give the crude product, which was purified by column chromatography to afford diphenyldisulfone in 58% yield. Preparation of diphenylthiosulfonate: To a mixture of Sm powder (3 mmol) in freshly distilled N,N-dimethylformamide (DMF, 10 mL), benzenesulfonyl chloride (2 mmol, freshly distilled) was added at 5°C with magnetic stirring under a nitrogen atmosphere. The resulting solution turned yellow-green within 15 min and an exothermic reaction was observed. After the completion of the reaction (about 1 h at 5°C), a routine workup as mentioned above afforded diphenylthiosulfonate in 87% yield. Preparation of diphenyldisulfide: To a mixture of Sm powder (4 mmol) in freshly distilled N,N-dimethylformamide (DMF, 10 mL) benzenesulfonyl chloride (2 mmol, freshly distilled) was added at 50°C with magnetic stirring under a nitrogen atmosphere. The resulting solution turned yellow-green within 1 min and an exothermic reaction was observed. After the completion of the reaction (about 10 min), a routine workup as mentioned above afforded diphenyldisulfide in 93% yield.
