Yield:12150-46-8 94%
Reaction Conditions:
with tributylphosphine;iodine in tetrahydrofuran;acetonitrile at 20; for 0.166667 h;Inert atmosphere;
Steps:
4
EXAMPLE 4100 mg (0.171 mmol) of l,l'-Bis(diphenyloxyphosphino)ferrocene were treated with I2 4 mg (16 μιηο) and tributylphosphine 170 μ^ (0.68 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 H20 (100 μ). The reaction mixture was diluted with ethyl acetate (lOmL) and was washed with portions of sat. NaHC03 (3x5 mL). The organic fraction was dried with Na2S04, filtered and the solvent evaporated under vacuum. The resulting residue was recrystallized from ethanol, the resulting crystals were filtered, washed and dried in vacuum, giving 89 mg (0.160 mmol, 94%>) of Ι,Γ- Bis(diphenylphosphino)ferrocene (dppf).
