| Abstract: | Two dianionic amine bis(phenolate) ligands are introduced and their reactions with titanium tetra(iso-propoxide) studied; ligand 1 having a single N-donor group leads exclusively to a homoleptic Lig2Ti type complex whereas ligand 3 having an additional N-donor on a side arm leads exclusively to a LigTi(OPri)2 type complex. |
