Synthesis of mono-substituted alkylcyclopentadienes by mixing alkyl iodides with cyclopentadienyl magnesium chloride in tetrahydrofuran is described.

Synthesis of mono-substituted cyclopentadienes

A process for preparing a cyclopentadienyl or indenyl ruthenium complex by treatment of a cyclopentadienyl or indenyl compound with ruthenium trichloride dihydrate and magnesium powder in an alkanol at 10&deg; C. to &minus;30&deg; C. is described.

Synthesis of bis (cyclopentadienyl) and bis (indenyl) ruthenium complexes

Conversion of cyclopentadienyl or indenyl compounds to titanium organometallic complexes by treatment with titanium tetraalkoxides is described.

Conversion of cyclopentadienyl silyl amines to organometallic complexes comprising titanium bisalkoxy moiety or titanium dichloride moiety

Cyclopentadienyl or indenyl titanium trichlorides are produced by converting a cyclopentadiene or an indene to a corresponding cyclopentadienyl or indenyl titanium trialkoxide which is treated with a halogenating agent to provide the desired cyclopentadienyl or indenyl titanium trichloride.

Preparation of cyclopentadienyl or indenyl titanium trihalides

Conversion of a ligand of titanium organometallic complex to a titanium bisalkoxy or a titanium dichloride is described.
