We report a novel, high yield one-step synthesis of water stable and solubl
e titanocene dichloride dihydrochloride salts from the direct reaction of t
he neutral amino-substituted cyclopentadienes with TiCl4. The following nov
el complexes have been synthesised: C5H4(CH2)(2)N(CH (2))(5)](2)TiCl2 (5),
[C5H4CH(CH (2))(4)NMe](2)TiCl2, (6), [C5H4(CH (2))(2)N(CH (2))(5)](2)TiCl2
. 2HCl (7), [C5H4CH(CH2)(4)](2)NMeTiCl2 . 2HCl (8), [C5H4(CH2)(2)N(CH2)(5)]
