The reaction of lithium [1,3-di(tert-butyl)cyclopentadienide] with titanium(IV) chloride in a xylene/hexanes mixture gives orange-red plates of [Ti{η5-1,3-(t-Bu)2C5H3}Cl3] (8, Cp=1,3-(t-Bu)2C5H3) in 70% yield (Scheme 32).[‌161‌] In 1967, King reported the synthesis of [TiCp*Cl3] (6) from pentamethylcyclopentadiene, butyllithium, and titanium(IV) chloride.[‌162‌] Trialkoxy complexes [TiCp(OR1)3] (R1=Et, Bu) can also be prepared by this method. As in the synthesis of dichlorobis(η5-cyclopentadienyl)titanium(IV) (78), other metal cyclopentadienide complexes (MCp, M=Na, Mg, SiR13) can also be used for the synthesis of trichloro(η5-cyclopentadienyl)titanium(IV) (79).[‌1‌]
