双苯磺酸甲烷

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of bis(phenylsulfonyl)methane (30 g, 100 mmol), tetra-n-butylammonium bromide (3 g, 9.3 mmol), 1,3-dibromopropane (30 ml), dichloromethane (600 ml) and 50% aqueous sodium hydroxide (150 ml) was stirred at room temperature for 3 days. The mixture was poured onto saturated aqueous ammonium chloride solution and extracted into dichloromethane. The combined organic extracts were dried (Na2SO4) and concentrated. The residue was crystallised from i-hexane:diethyl ether to give the title product as a white solid. Yield−24 g (71%). extracted into dichloromethane The combined organic extracts were dried (Na2SO4) concentrated The residue was crystallised from i-hexane
