Dicarbonylbis(cyclopentadienyl)titanium is the chemical compound with the formula (η5-C5H5)2Ti(CO)2, abbreviated Cp2Ti(CO)2. This maroon-coloured, air-sensitive species is soluble in aliphatic and aromatic solvents. It has been used for the deoxygenation of sulfoxides, reductive coupling of aromatic aldehydes and reduction of aldehydes.

Structure and synthesis

Cp2Ti(CO)2 is prepared via the reduction of titanocene dichloride with magnesium under an atmosphere of carbon monoxide.

(C5H5)2TiCl2 + Mg + 2 CO → (C5H5)2Ti(CO)2 + MgCl2

Both Cp2Ti(CO)2 and Cp2TiCl2 are tetrahedral as are related zirconium and hafnium compounds.
