rust-brown to brown fine powder | [Uses]
Catalyst for coupling reactions of organic halides, organometallic Compounds and also for the cyclooligomerization of cumulenes;. | [Uses]
Tetrakis(triphenylphosphine)nickel(0) is a catalyst for coupling reactions of organic halides, organometallic compounds and also for the cyclooligomerization of cumulenes. | [Preparation]
The standard preparation of Tetrakis(triphenylphosphine)nickel involves the reduction of Nickel(II) Acetylacetonate with Triethylaluminum in the presence of Triphenylphosphine. To 21.3 g of anhydrous Ni(acac)2 and 125 g PPh3 in 800 mL of Et2O under N2 at 0°C is slowly added 28.0 g Et3Al. The reddish-brown precipitate is collected, washed with Et2O, and twice dissolved in benzene and reprecipitated by the addition of n-heptane to give about 50 g (55%) of Ni(PPh3)4.
| [reaction suitability]
core: nickel
reagent type: catalyst | [storage]
Tetrakis(triphenylphosphine)nickel is highly oxygen sensitive. Special inert-atmosphere techniques must be used. Should be stored at 0 °C. Cancer suspect agent.
