The reaction of lithium [1,2,4-tris(trimethylsilyl)cyclopentadienide] with the titanium(III) chloride–tris(tetrahydrofuran) complex in tetrahydrofuran affords the turquoise titanium(III) complex [Ti{η5-1,2,4-TMS3C5H2}Cl2], which is oxidized by hydrogen chloride to give orange crystals of [Ti{η5-1,2,4-TMS3C5H2}Cl3] (8, Cp′ = 1,2,4-TMS3C5H2) in a 60% yield (Scheme 36).[170,171] In comparison, the reactions of lithium [1,3-di(tert-butyl)cyclopentadienide] or lithium [1,2,4-tris(trimethylsilyl)cyclopentadienide] with titanium(IV) chloride failed and gave intractable products. [Ti(η5-iPrC5Me4)Cl3] (8, Cp′ = iPrC5H4) has been synthesized in a 66% yield by a similar method, namely reaction of lithium (isopropylcyclopentadienide) with the titanium(III) chloride–tris(tetrahydrofuran) complex, followed by oxidation with hydrogen chloride (Scheme 36).[172]
