N-Donor ligand activation of titanocene for the Biginelli reaction via the imine mechanism

The remarkable activation of stable titanocene dichloride (Cp(2)TiCl(2)) was achieved using N-donor ligand urea in an alcoholic solvent, leading to the formation of a Ti(iv) species [(MeO)(2)Ti(NHCONH(2))](+), the existence of which was verified by ESI-MS, ESI-MS/MS, and NMR. Catalyzed by the newly...
