Abstract
A method for producing a titanocene wherein a TiCl3 complex free from salts of metals other than titanium is reacted with a titanocene ligand.
Claims4
In a process for producing a titanocene
- wherein a titanium trichloride reagent is reacted with a ligand to produce a titanocene, the improvement which comprises utilizing as said titanium trichloride reagent, a titanium trichloride complex produced by treatment of titanium tetrachloride with particulate titanium in the presence of a reagent which forms a titanium trichloride complex
- wherein a titanium trichloride complex free of contamination with a salt of a metal other than titanium is produced.
