Titanium(II) complex CpTiCl(dmpe)$\sb2$ is prepared by reducing (CpTiCl$\sb2)\sb{\rm x}$ with n-butyllithium in the presence of 1,2-bis(dimethylphosphino)ethane (dmpe). Subsequent treatment with methyllithium or n-butyllithium affords CpTiMe(dmpe)$\sb2$ and CpTiH(dmpe)$\sb2$, respectively. The crystal structures of CpTiX(dmpe)$\sb2$ (X = Cl, Me, H) show unusually long metal ligand distances. Analogous treatment of (Cp$\sp*$Ti(BH$\sb4$)Cl) $\sb2$ with n-butyllithium affords Cp$\sp*$Ti(BH$\sb4$)(PP), where PP is dmpe or (t-butyl)tris(dimethylphosphino-methyl)silane. All of these titanium(II) complexes catalyze oligomerization of ethylene to 1-butene, 2-ethyl-1-butene, and 3-methyl-1-pentene, probably via metallacyclopentane intermediates.
