92% With silica bromide In dichloromethane at 20℃; for 0.166667 h; Inert atmosphere General procedure: In a typical procedure, diphenyl sulfoxide (2.2 g, 0.01 mol) and brominated silica (18.18 g, 40 mmole Br/g silica) are mixed in an aprotic solvent, e.g. dichloromethane (2 mL) or carbon tetrachloride, at room temperature with exclusion of atmospheric moisture, for 5 min. Diphenyl sulfide is isolated in pure state by simple filtration and evaporation of the solvent (1.84, 99percent).
90% With tantalum pentachloride; sodium iodide In acetonitrile at 20℃; for 0.0833333 h; General procedure: In a 10 mL round-bottom flask, to a solution of diphenylsulfoxide (202 mg, 1.0mmol) in CH3CN (4 mL), tantalum (IV) chloride (179 mg, 0.5 mmol) and sodium iodide (300 mg, 2.0 mmol) were added at room temperature. The mixture turned dark brown almost immediately and the progress of the reaction was followed by TLC. After completion of the reaction (3 min), the reaction mixture was diluted with water and then extracted with ethyl acetate. The combined organic extracts were washed successively with 10percent aq Na2S2O3 and H2O. The organic layer was separated and dried over anhydrous Na2SO4 and concentrated under reduced pressure.

The whole mixture was stirred for 3 h at room temperature and the progress of the reaction was followed by TLC. On completion, the solvent was removed under reduced pressure and the residue was extracted successively with ethyl acetate, washed with water and brine. The organic layer was separated, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was purified by column chromatography on a silica gel (hexane:ethyl acetate = 2:1) to afford diphenylsulfide (88 mg, 95percent).

The crude product was purified by column chromatography[silica gel, hexane–Et2O (99:1)]. In the formation of somebenzaldehydes, low isolated yields were observed because ofinstability of the benzaldehydes on silica gel

92% at 130℃; for 12 h; Sealed tube; Inert atmosphere General procedure: An oven dried pressure tube was chargedwith aryl bromide (1 mmol), CuI (1 mmol), DABCO (2 mmol) and dry DMSO (5 mL).Then the tube was sealed with a teflon cap and heated with stirring at 130 Cin N2 atmosphere for 12 – 36 h. The completions of reactions weremonitored by TLC. The reaction mixture was then cooled to room temperature. Themass was passed through celite bed, packed in a sinter funnel. Then thefiltered reaction mixture was extracted with ethyl acetate (3 X 20) washed withwater (3 X 20) and brine solution (3 X 10). Ethyl acetate part were collectedand dried over Na2SO4, and then evaporated under reducedpressure. The crude products were purified by column chromatography on silicagel to obtain pure product.
70% at 135℃; for 36 h; General procedure: An oven dried pressure tube was charged with aryl halide (0.5mmol), CuI (10–25molpercent), anhydrous Zn(OAc)2 (1.5–2equiv) and anhydrous DMSO (1.6mL). The tube was sealed with a Teflon screw cap and stirred at 135°C for 24–36h. The reaction mixture was then cooled to room temperature and stirred in 10mL of diethyl ether for 5min. It is filtered through a sintered funnel and the filtrate is washed with excess ice cold water and further extracted with diethyl ether (3×10mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give the crude product, which was purified by column chromatography using 200–400 mesh silica gel and a mixture of diethyl ether and hexane (or pentane, for Table 2, entries 2, 8, 10, 14, 16 and 24) as eluents to afford the desired products in good yields.

60% With N-ethyl-N,N-diisopropylamine In water at 189℃; for 48 h; General procedure: To a round bottomed flask equipped with magnetic stir bar and reflux condenser were added: the aryl halide (2.0 mmol), dimethylsulfoxide (10 mL), N,N-diisopropylethylamine (0.35 mL, 2.0 mmol), and water (approximately 0.04 mL, 2.0 mmol). The reaction was heated to reflux temperature (189 °C) in a sand bath and stirred for the specified time. Reaction progress was monitored by TLC and/or 1H NMR analysis. When complete consumption of the starting material was evident, the reaction was cooled to room temperature extracted with ethyl acetate (x3) and the combined organic extracts were washed with 2 M HCl, brine, and dried over MgSO4.The solvent was removed en vacuo and the crude product was purified by column chromatography on silica gel (Hexanes/EtOAc, gradient elution).

89.2% at -5 - 45℃; for 7 h; In a 500 mL dry three-necked flask, add DMF (150 mL), thioanisole (100.0 g), and cool to -5°C -5°C.150.0 g of phosphorus oxychloride was slowly added dropwise. During the addition, the internal temperature was kept between -5°C and 5°C. After the dripping is completed,Slowly raise the reaction temperature between 35-45°C, stir the reaction for 7 hours, and check the reaction by TLC.After the reaction was completely completed, the reaction solution was cooled to room temperature, and the reaction solution was slowly added to 500 mL of ice water, keeping the temperature not higher than 35°C.After the completion of the transfer, and stirring at not more than 35 ° C for 10 minutes, add 200mL of dichloromethane, with 10percent sodium hydroxide to adjust the pH to 7-8, separate the organic phase,Continue to extract once with 200 mL of methylene chloride. Combine the organic phases and dry over anhydrous sodium sulfate.The organic solvent was distilled off, distillation was continued, and a fraction between 85-90°C was collected to obtain 109.4 g of a colorless transparent liquid in a yield of 89.2percent.
