Titanocene dichloride Usage And Synthesis

Reaction

  1. Precatalyst for reduction of esters and α,β-unsaturated ketones.
  2. Catalyzes reductive deoxygenation of alcohols and hydroxylamines.
  3. Catalyst for the radical cyclization of epoxides.
  4. Reagent for the conversion of enynes to bicyclic cyclopentenones.
  5. Catalyzes silylation of alkenes and alkynes.

Chemical Properties

Titanocene dichloride is irritating to the skin and mucous membranes.

Chemical Properties

Red crystals. Moderately soluble in toluene, chloroform; sparingly soluble in ether and water. Stable in dry air, slowly hydrolyzed in moist air.

Uses

Catalyst; with aluminum alkyls as Ziegler-Natta polymerization catalyst.

Uses

Titanocene dichloride is used as an experimental cancer chemotherapeutic agent.

Production Methods

Titanocene dichloride is produced by the reaction of titanium tetrachloride with cyclopentadienyl sodium.

General Description

Red to red-orange crystals.

Air & Water Reactions

Stable in dry air. Decomposes in moist air and in water to form HCl .

Reactivity Profile

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.

Fire Hazard

Flash point data for Titanocene dichloride are not available; however, Titanocene dichloride is probably combustible.

Safety Profile

Poison by intravenous and intraperitoneal routes. Questionable carcinogen with experimental neoplastigenic, tumorigenic, and teratogenic data. Mutation data reported. See also TITANIUM COMPOUNDS. When heated to decomposition it emits toxic fumes of Cl-

Carcinogenicity

Based on the results of 2 year gavage studies, the National Toxicology Program determined that there was equivocal evidence of the carcinogenic activity of titanocene dichloride in male and female rats based on a marginal increase in the incidence of forestomach squamous cell effects.

Carcinogenicity

Titanocene administered by intramuscular injection produced tumors both at the injection site and at sites distant from the injection site. Titanocene dichloride showed equivocal evidence of carcinogenicity in male and female Fischer 244 rats in a 2-year oral gavage study.

Purification Methods

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.
