Abstract

The new titanium(IV) coordinative compound (dpp-bian)TiCl2 (2) was obtained by metathesis of the disodium salt (dpp-bian)Na2 (1) (dpp-bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) with TiCl4. It was shown that the chlorido ligands can be exchanged for chelating dpp-bian ligands, or tert-butoxy groups, with the formation of (dpp-bian)2Ti (3) and (dpp-bian)Ti(OtBu)2 (4), respectively. Complexes 2–4 were isolated and fully characterized. It was demonstrated that dpp-bian is in the reduced dianionic form and acts as a σ2π-donor ligand.
