Preparation and reactions
(C5H5)TiCl3 is prepared by the reaction of titanocene dichloride and titanium tetrachloride:
- (C5H5)2TiCl2 + TiCl4 → 2 (C5H5)TiCl3
The complex is electrophilic, readily forming alkoxide complexes upon treatment with alcohols.[2]
Reduction of (cyclopentadienyl)titanium trichloride with zinc powder gives the polymeric Ti(III) derivative (cyclopentadienyl)titanium dichloride:[3]
- (C5H5)2TiCl2 + 0.5 Zn → 1/n [(C5H5)TiCl3]n + 0.5 ZnCl2
