Iodine → Tris(4-chlorophenyl)phosphine

참여 물질

반응 단계

100 mg (0.262 mmol) of tris(4-chlorophenyl)phosphineoxide were treated with 6 mg I2 (26 μmol) and tributylphosphine 130 μL (0.52 mmol) in acetonitrile/THF (1:1 v/v) 1 mL. The mixture was stirred at room temperature for 10 minutes under nitrogen atmosphere before it was quenched with H2O (100 μL). The reaction mixture was diluted with ethyl acetate (10 mL) and was washed with portions of sat. NaHCO3 (3×5 mL). The organic fraction was dried with Na2SO4, filtered and the solvent evaporated under vacuum. The resulting residue was recrystallized from methanol (2 mL), the resulting crystals were filtered, washed and dried in vacuum, giving 95 mg (0.260 mmol, 99%) of tris(4-chlorophenyl)phosphine.
