Chemische Eigenschaften
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.
Verwenden
Nickelocene is obtained through reacting nickel halides with
sodium cyclopentadienide. It is used as a catalyst or as a
complexing agent.
Allgemeine Beschreibung
Dark liquid in an 8-10% solution in toluene. Insoluble in water.
Air & Water Reaktionen
Highly flammable. The neat material is sensitive to air. . Insoluble in water.
Reaktivit?t anzeigen
Organometallics, such as NICKELOCENE, 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.
Hazard
Toxic by inhalation and skin contact, a carcinogen (OSHA).
Health Hazard
ACUTE/CHRONIC HAZARDS: NICKELOCENE can be absorbed through the skin.
Brandgefahr
NICKELOCENE is flammable.
Sicherheitsprofil
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data. Poison
by intraperitoneal and intramuscular routes.
Moderately toxic by ingestion. When heated
to decomposition it emits acrid smoke and
irritating fumes. See also NICKEL
COMPOUNDS.
l?uterung methode
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.]
