The reduction of [Ti(Cp*)Cl3] (6) by sodium/naphthalene in the presence of bis(dimethylphosphino)ethane, followed by treatment with carbon monoxide (1 × 105 Pa) gives [Ti(Cp*)Cl(CO)2(DMPE)]. This compound has been characterized by IR and NMR spectroscopic methods and is rather unstable, whereas the structure of the analogous hafnium complex could be confirmed by X-ray diffraction.[‌249‌]
