light yellow crystals or crystalline powder
Catalyst for:
- Cyclotrimerization reactions
- Cyclooligomerization reactions
Catalyst in polymerization of acetylene to benzene and styrene, trimerization of ethynyl Compounds, cyclization of butadiene.
core: nickel
reagent type: catalyst
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.
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.
