Synthesis

12150-46-8

The general procedure for the synthesis of 1,1'-bis(diphenylphosphino)ferrocene (dppf) from the compound (CAS: 405164-68-3) is as follows: Example 4: 100 mg (0.171 mmol) of 1,1'-bis(diphenoxyphosphino)ferrocene was reacted with 4 mg (16 μmol) of I? and 170 μL (0.68 mmol) of tributylphosphine in 1 mL of acetonitrile/THF (1:1, v/v) mixed solvent. The reaction mixture was stirred at room temperature for 10 min under nitrogen protection, followed by quenching the reaction with 100 μL of H?O. The reaction was then quenched with 10 mL of ethyl acetate. The reaction mixture was diluted with 10 mL of ethyl acetate and washed three times (5 mL each) with saturated aqueous NaHCO?solution. The organic phase was dried with Na?SO?, filtered and concentrated under reduced pressure. The resulting residue was recrystallized with ethanol, the crystals were collected by filtration, washed and dried under vacuum to give 89 mg (0.160 mmol, 94% yield) of 1,1'-bis(diphenylphosphino)ferrocene (dppf).

Purification Methods

Wash it with distilled H2O and dry it in a vacuum. Dissolve it in ca 5 parts of hot dioxane and cool to give orange crystals m 181-183o. Recrystallisation from *C6H6/heptane (1:2) gives a product with m 183-184o. [Bishop et al. J Organomet Chem 27 241 1971.]
