43% | With potassium iodide; sulfuric acid; urea; sodium nitrite; In dichloromethane; water; | EXAMPLE 1 Preparation of 3,3'-diiododiphenyl sulfone The reaction is performed in a 1 L beaker equipped with a magnetic stirring bar and cooled to 0 C. in an ice bath. The beaker is charged with sulfuric acid (12 mL. 95% w/w), water (55 mL), and <strong>[599-61-1]3,3'-diaminodiphenyl sulfone</strong> (15.0 g, 60.4 mmol). The mixture is stirred until the sulfone is completely dissolved (approximately 20 minutes), and the temperature is kept at 0 C. with the addition of 20 g of ice. Sodium nitrite (8.34 g, 121 mmol) in water (40 mL) is added dropwise below the surface of the reaction mixture, keeping the temperature below 5 C. The color darkens somewhat after the addition is complete, and it is left to stir for 10 minutes. Urea (0.25 g) is added to remove any of the excess sodium nitrite from solution. Potassium iodide (20.06 g, 121 mmol) in water (40 mL) is added slowly to the reaction mixture. Immediately gas evolution is evident, and the mixture turned dark brown. The mixture is left to stir for 3 hours until gas evolution subsided. The aqueous layer is removed, and the organic layer is washed with 10% NaOH (500 mL). Then it is diluted with CH2 Cl2 and washed with water (2 L) and saturated NaHCO3 (500 mL). Drying (MgSO4), filtration and solvent removal on the rotary evaporator afforded 21.2 g of a dark solid. This solid is dissolved in CH2 Cl2 and 10.0 g of decolorizing carbon is added. The carbon is filtered off, and the solvent is removed to leave 16.4 g of a yellow solid. It is recrystallized from methanol, and then passed through a short silica gel column with CH2 Cl2 as the eluent to leave 12.2 g (43% yield) of a white crystalline solid, m.p. 110-114 C. IR, 1 H-NMR, and 13 C-NMR data are consistent with the structure of STR6 |
