(Cyclopentadienyl)titanium trichloride is an
organotitanium compound with the formula (CH)TiCl. It is a moisture sensitive orange solid. The compound adopts a
piano stool geometry.
Preparation and reactions
is prepared by the reaction of
titanocene dichloride
Titanocene dichloride is the organotitanium compound with the formula (hapticity, ''η''5-C5H5)2TiCl2, commonly abbreviated as Cp2TiCl2. This metallocene is a common reagent in organometallic and organic synthesis. It exists as a bright red solid t ...

:
The complex is electrophilic, readily forming
alkoxide complexes upon treatment with alcohols.
Reduction of (cyclopentadienyl)titanium trichloride with zinc powder gives the polymeric Ti(III) derivative (cyclopentadienyl)titanium dichloride:
:
A related reduction can be effected with
cobaltocene:
:
Other evidence for the
Lewis acidity of the trichloride is the ready formation of adducts with
phosphine ligands:
