General Description
Dark liquid in an 8-10% solution in toluene. Insoluble in water.
Reactivity Profile
Organometallics, such as NICKELOCENE(1271-28-9), are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases.
Air & Water Reactions
Highly flammable. The neat material is sensitive to air. . Insoluble in water.
Hazard
Toxic by inhalation and skin contact, a carcinogen (OSHA).
Health Hazard
ACUTE/CHRONIC HAZARDS: This chemical can be absorbed through the skin.
Fire Hazard
This chemical is flammable.
Chemical Properties
GREEN TO DARK GREEN CRYSTALS OR CRYST. POWDER
Chemical Properties
Nickelocene is a solid crystalline substance of dark green
color, insoluble in water or carbon tetrachloride, slightly
soluble in alcohol and liquid ammonia, and readily soluble in
nonpolar organic solvents.
Purification Methods
Dissolve the complex in Et2O, filter and evaporate in a vacuum. Purify it rapidly by recrystallisation from pet ether using a solid CO2/Me2CO bath, m 171-173o(in an evacuated tube). Also purify it by vacuum sublimation. [Wilkinson et al. J Am Chem Soc 76 1970 1954, Beilstein 16 IV 1831.]
