Route of Synthesis (ROS)
| Conditions | Yield |
| Stage #1: XPhos With sulfuric acid; sulfur trioxide In dichloromethane at 0 – 20℃; for 24h; Cooling with ice; Stage #2: With sodium hydroxide In dichloromethane; water at 0℃; pH=~ 7.0; Cooling with ice; Experimental Procedure To an oven-dried 25 mL round bottom flask equipped with a Teflon-coated magnetic stir bar and rubber septum was added dicyclohexyl-(2′,4′,6′-triisopropyl-biphenyl-2-yl)-phosphane (476 mg, 1.00 mmol) and CH2Cl2 (1.0 mL). The solution was cooled to 0° C. using an ice/water bath and then concentrated H2SO4 (1.00 mL) and fuming sulfuric acid (3.0 mL, 20% SO3) were added dropwise. The solution was allowed to warm to room temperature and stir for 24 h. At this time it was cooled to 0° C. using an ice/water bath and crushed ice (10 g) was added. The solution turned cloudy and white in color. An aqueous solution of NaOH (6.0 M, 20.0 mL) was then added dropwise to the cooled solution until it became neutral (pH 7.0 as judged by pH paper). The aqueous solution was extracted with CH2Cl2 (3×50 mL) and concentrated under reduced pressure to give a beige solid. The crude material was then dissolved in a minimum amount of cold methanol (20 mL), filtered and concentrated (this cycle was repeated) to give sodium 2′-(dicyclohexyl-phosphanyl)-2,6-diisopropyl-biphenyl-4-sulfonate (4) as a beige solid (503 mg, 94%).
