Dicyanobis(triphenylphosphine)nickel(II) is a nickel(II) complex useful for the oligomerization of norbornadiene and the isomerization of olefins. | [Preparation]
Dry nickel(II) cyanide (11 g) was refluxed in 1 L ethanol with 78 g Triphenylphosphine for 48 h. The yellowish-gray Ni(CN)2 turned to a light yellow coarse crystalline mass. The solvent was decanted and the solid was rinsed with ethanol to remove unreacted PPh3. The remaining solid product was dried, extracted with CH2Cl2, and filtered to exclude insoluble Ni(CN)2. Removal of solvent provided 39 g (62%) of Dicyanobis(triphenylphosphine)nickel(II). |
