(Cyclopentadienyl)titanium trichloride is an organotitanium compound with the formula (C5H5)TiCl3. It is a moisture sensitive orange solid. The compound adopts a piano stool geometry.[1]

Preparation and reactions[edit]

(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
