reaction type: Cross Couplings | | Synthesis | The general procedure for the synthesis of tris(4-chlorophenyl)phosphine oxide from tris(4-chlorophenyl)phosphine oxide was as follows: 5100 mg (0.262 mmol) of tris(4-chlorophenyl)phosphine oxide was reacted with 6 mg of I (26 μmol) and 130 μL (0.52 mmol) of tributylphosphine in 1 mL of mixed solvent of acetonitrile/THF (1:1, v/v) under nitrogen protection The reaction was carried out at room temperature for 10 min. After stirring for 10 min at room temperature, the reaction was quenched with 100 μL HO. The reaction mixture was diluted with 10 mL of ethyl acetate and washed three times (5 mL each) with saturated aqueous NaHCOsolution. The organic phase was dried with NaSO, filtered and concentrated under reduced pressure. The residue was recrystallized with 2 mL of methanol, the crystals were collected by filtration, washed and dried under vacuum to give 95 mg (0.260 mmol, 99%) of tris(4-chlorophenyl)phosphine. | | References | [1] Patent: WO2011/123037, 2011, A1.
