BIS(TRIPHENYLPHOSPHINE)DICARBONYLNICKEL Usage And Synthesis

Chemical Properties

light yellow crystals or crystalline powder

Uses

Catalyst for:

• Cyclotrimerization reactions
• Cyclooligomerization reactions

Uses

Catalyst in polymerization of acetylene to benzene and styrene, trimerization of ethynyl Compounds, cyclization of butadiene.

reaction suitability

core: nickel
reagent type: catalyst

Synthesis

The preparative method of Bis(triphenylphosphine)dicarbonylnickel: by treating Tetracarbonylnickel with 2 equiv of Triphenylphosphine or by dissolving Dichlorobis(triphenylphosphine)nickel(II) in ethanol and treating it with CO in the presence of MeSNa. Purification: recrystallize from benzene.

Precautions

Catalytic activity decreases with storage. It is likely to be toxic, similar to nickel carbonyl, but its low volatility makes it easy to avoid ingestion. Use in a fume hood.
