摘要:
Treatment of water-stable Cp2TiMe2 with [Ph3C]-[B(C6F5)(4)] in CD2Cl2 gives the solvent-separated ion pair [Cp2Ti(Me)(CD2Cl2)][B(C6F5)(4)], which reacts rapidly with water at 205 K to give the corresponding aqua complex [Cp2Ti(Me)(H2O)][B(C6F5)(4)]. The latter has been characterized by H-1 and C-13 NMR spectroscopy at 205 K and is a rare, possibly unique, example of a complex containing aqua and methyl ligands within the coordination sphere of a titanium(IV) complex.
