Beschreibung
Titanocene dichloride is an organotitanium compound with the chemical formula (η5-C5H5)2TiCl2, often written as Cp2TiCl2, which is a common reagent in organometallic chemistry and organic synthesis. Cp2TiCl2 does not form a "sandwich" structure like ferrocene, but a tetrahedral structure due to its four ligands around a metal center. Because of its anti-tumor activity, it has been used in clinical trials as a chemotherapeutic agent.
Chemische Eigenschaften
Titanocene dichloride is a reddish-orange crystalline solid. Moderately soluble in toluene, chloroform, alcohol, and other hydroxylic solvents; sparingly soluble in water, petroleum ether, benzene, ether, carbon disulfide, and carbon tetrachloride. Stable in dry air, slowly hydrolyzed in moist air. Titanocene dichloride is irritating to the skin and mucous membranes.
Verwenden
Titanocene dichloride is used as an experimental cancer chemotherapeutic agent. It is used as a research chemical, as a catalyst in Ziegler–Natta polymerization reactions, and as an implant material in orthopedics, oral surgery, and neurosurgery.This metallocene is a common reagent in organometallic and organic synthesis. Titanocene dichloride is used to prepare titanocene pentasulfide. Used as an anticancer drug.
Vorbereitung Methode
Titanocene dichloride is produced by the reaction of titanium
tetrachloride with cyclopentadienyl sodium.
Allgemeine Beschreibung
Titanocene dichloride appears as red to red-orange crystals. (NTP, 1992)
Air & Water Reaktionen
Stable in dry air. Decomposes in moist air and in water to form HCl .
Reaktivität anzeigen
Titanocene dichloride is incompatible with strong oxidizers. Titanocene dichloride may decompose on exposure to water. .
Hazard
Toxic by inhalation, irritant to skin and
mucous membranes.
Brandgefahr
Flash point data for Titanocene dichloride are not available; however, Titanocene dichloride is probably combustible.
Sicherheitsprofil

läuterung methode
It forms bright red crystals from toluene or xylene/CHCl3 (1:1) and sublimes at 190o/2mm. It is moderately soluble in EtOH and insoluble in Et2O, *C6H6, CS2, CCl4, pet ether and H2O. The crystalline dipicrate explodes on melting at 139-140o. [Wilkinson et al.
