Infobox references

(Pentamethylcyclopentadienyl)titanium trichloride is an organotitanium compound with the formula Cp*TiCl3 (Cp* = C5(CH3)5). It is an orange solid. The compound adopts a piano stool geometry. An early synthesis involve the combination of lithium pentamethylcyclopentadienide and titanium tetrachloride.[2]

The compound is an intermediate in the synthesis of decamethyltitanocene dichloride. In the presence of organoaluminium compounds and other additives, it catalyzes the polymerization of alkenes.[3][4]
