Decamethyltitanocene dichloride is an organotitanium compound with the formula Cp*2TiCl2 (where Cp* is C5(CH3)5, derived from pentamethylcyclopentadiene). It is a red solid that is soluble in nonpolar organic solvents. The complex has been the subject of extensive research. It is a precursor to many organotitanium complexes. The complex is related to titanocene dichloride, which lacks the methyl groups.
The complex is prepared by the reaction of titanium tetrachloride with LiCp*. An intermediate in this synthesis is (pentamethylcyclopentadienyl)titanium trichloride.
Reduction of Cp*2TiCl2 in the presence of ethylene gives the adduct Cp*2Ti(C2H4). [1] The analogous Cp compound has not been prepared, a contrast that highlights the advantages of the Cp* ligand. This pentamethylcyclopentadienyl (Cp*) species undergoes many reactions such as cycloadditions of alkynes. [2]
The dicarbonyl complex Cp*2Ti(CO)2 is prepared by reduction of Cp*2TiCl2 in the presence of carbon monoxide. [3]
