実験手順

Biphenyl-4-ol((5.26 g, 30.9 mmol), sodium iodide (4.635 g, 30.9 mmol), sodium hydroxide (1.276 g, 31.9 mmol) was dissolved in methanol (85 mL) and cooled to 0° C. To the solution was added 12% (w/v) sodium hypochlorite (20 mL) dropwise maintaining the temperature below 4° C. The solution was stirred at this temperature for 1 hour and then 2M sodium thiosulfite (50 mL) wad added and the pH of the solution was adjusted to >pH 7 with 1M HCl. The mixture was filtered and the filtrate was washed with water. The solid was dried in a vacuum oven and then the title product was obtained as crystals after recrystallisation from heptane. Yield 7.08 g, 77%.
