Cp*FvTiCl (1; Cp* = eta-5-C5H5, Fv = eta-6-C5Me4CH2) reacts with benzaldehyde, yielding Cp*Ti[(OCHPh)2C5Me4(CH2)]Cl (2) as the result of insertion in two Ti-C bonds at the 2- and 4-positions of the fulvene ligand in 1. Complex 2 reacts with HCl to give Cp*TiCl3 (3) and the corresponding dialcohol and with TiCl4 to give 3 and Ti[(OCHPh)2C5Me4(CH2)]Cl2 (5). X-ray diffraction analysis of 5 shows it to be a dialkoxide-dichloride monomeric titanium complex with a tetrahedral arrangement of the ligands around the metal center.
