Synthesis of titanium(IV) (cyclopentadienylalkyl)aminate complexes

We describe the synthesis of hydrochlorides of [TiCp{(C5H4(CH2)nNMe2}Cl2] (n=2 or 3) via [TiCpCl3] and the lithiated (cyclopentadienylalky)lamine. The –NHMe2 groups in these complexes are not coordinated to the titanium, and probably not in the parent amines either, the metal stereochemistry being the same in each group of compounds. The structure of [TiCp(η5-C5H4CH2CH2CH2NHMe2)Cl2]Cl is described in detail.
